Hi,

If you like to write an xml-template by having purely xml, you could
also use OPT (Open Power Template).

You can f.e. add a attribute to a tag by decision by writing this code:

Feels a bit cleaner to me than writing

Hi, mirrys

Why not use the function filter_input()? This would be at least show
if the value is a valid ip-address.

function getIPadress() {
$params = array(
"HTTP_CLIENT_IP",
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"REMOTE_ADDR"
);

foreach($params as $param) {
if ($val = filter_input(INPUT_SERVER, $param, 
FILTER_VALIDATE_IP))
return $val;
}

return false;
}

This way you could even specify "I don't want ip's out of a private
range" and stuff like that ...
http://www.php.net/manual/en/filter.filters.validate.php
http://www.php.net/manual/en/function.filter-input.php

If no valid ip-address is found you'll get false here ... depends -
may you want to give "127.0.0.1" back then ;)

Hi, Mirrys

I personally can not see a security-hole at the first view ...
Stuff in the global server-variable should only be set by the
webserver and therefore it should be kind-of save (depending on the
quality of the configuration of the webserver ;))

That was also the main reason why I would do a validation-check for this.
Talking about a script-crash ... I don't know ... I just found this

Hi, Ethan

The only thing I can come up with, that would really help you, since
you're just working with var_dump and print_r, is a php-debugger.

The common debugger for php are Zend Debugger and xdebug.

Nearly every IDE can be connected to them and if you set it up
correctly you can browse through your side (using your favourite
browser) and activate the debugger just by setting a cookie. For
several browsers there are plugins that set the cookie by clicking an
icon.
I'm talking about "nearly every IDE" because I saw a screenshot of
someone debugging a php-script using xdebug and vi :)

Just the first two links I found on google ...
* http://xdebug.org/docs/install
* 
http://www.thierryb.net/pdtwiki/index.php?title=Using_PDT_:_Installation_:_Installing_the_Zend_Debugger

Is that what you need?

I'm personally using PhpStorm and a VM with Debian, PHP 5.3 and xdebug
to debug my scripts and am perfectly fine with that. I can send you my
whole xdebug-config if you want :)

The stuff with javascript sounds like something automated to me ...
But I don't think you're talking about auto-form-fill and stuff like
that, are you?

Hi, Ethan

I forgot to mention that the whole configuration of my test-webserver
is on github ;) There are my configuration-files for apache, mysql,
nginx, php, solr and so on.
But I have to say that my environment is a bit special as I am
developing on a windows-machine and this configuration is running on a
virtual linux machine. Don't hesitate to ask things about the
configuration :)
https://github.com/SimonSimCity/webserver-configuration
For each program I have an init.sh script which will install the
program exactly the way I use it.
Feel free to fork it and add your stuff.

If you're just looking for the xdebug-configuration:
https://github.com/SimonSimCity/webserver-configuration/blob/master/php/conf/conf.d/xdebug.ini
You might have to change it to use it on a windows-environment ... at
least you'd have to move it into your php.ini file instead of an
separate configuration-file as it is on Linux.

As I am the only one developing on this machine, I've configured
xdebug in that way, that anyone can open a xdebug-debug-session. This
is done by enabling xdebug.remote_connect_back. Please do not use this
on your live-server, but set an ip-limit using xdebug.remote_host!

Please read this part of the xdebug-configuration to get a better
understanding on how to set up a working environment (specially the
part "Starting The Debugger"):
http://xdebug.org/docs/remote

The only problem I can report so far is, that I can't debug
command-line scripts ... If someone else reading that post has an
answer, I'd be glad to hear it.

Re: [PHP] requesting comments on rajmvServiceLog (access + error logging through PHP and JS to MySQL)

[Simon Schick]

Hi, Rene

I took a quick look over your code ...

I kind-of like the idea having all logging at one place, but the code is a
bit too messy if you ask me :)
If you would have put it on github and I would fork it - the first thing
I'd do is trying to get rid of the hm-lib and rewriting all in a bit more
object-oriented style, but that's just personal taste ;)
Specially the function rajmvServiceLog_graphs_raphael_calculateData() with
a code of ca. 280 lines is quite long ...
Additionally I think that setting an error-handler who's just returning
false is not a good way. Why not disable error-handling or write code that
produces no errors?

I think it would be good to mention that you're using the library adodb (
http://adodb.sourceforge.net/) and sitewide_rv (is it that?
http://mediabeez.ws/) or am I guessing wrong?

You're talking about a sql-file ... has my anti-virus-program removed
something here?

Please don't see that as destructive critic, but as hints what I would do
if I get to do with this code.

Simon

Re: [PHP] [missing] images .htaccess

[Simon Schick]

Hi, Muad

I guess that you have a cms (would be nice to name it if it's not a
custom one) that handles all requests coming into the system. Think
now of How you know if the requested uri is a missing-image and write
it down as mod_rewrite rule.
Is this the only line you have in your .htaccess-script? What does the
cms with the request if the file is available? Does the cms here just
works like a proxy or is it doing some other magic? May it checks some
permissions first before it ships the file?

If you want to ungo passing requests for images to the cms, I'd do it like this:
It checkes if the request is pointing to a directory where only images
(or downloadable files) are located and lets apache do the rest to
provide the file. Or check for file-endings ...

RewriteRule \.(gif|jpg|jpeg|png)$ - [L]

You can then guess that all files ending with .jpeg, .jpg, .gif, .png
or similar are pictures, bypass the cms and let apache ship the file
or apaches 404-page if not available.
But this has nothing to do with PHP itself but is an apache-configuration.
Here's a beginner guide where I copied the line above:
http://www.workingwith.me.uk/articles/scripting/mod_rewrite

Re: [PHP] Which workstation????

[Simon Schick]

Hi, Farzan

I do not really get your point of confusion ...

What you've posted here are tools/frameworks that do not to the same stuff
at all, yes you could even use all without missing something ...

cakephp
.. is a full-stack PHP-Framework. Yes, I have to say that there's quite a
bunch of full-stack frameworks in PHP you could choose and I myself would
recommend one by knowing how much experience you have in PHP :)

smarty
.. is a template-engine for PHP. If you want to use smarty, twig, php
itself or another library as template-engine is up to you. Using a
template-engine for some programmers I know just feel like a better
separation between the view and the controler/model (search for
ModelViewControler if you don't know what I mean here).

netbeans
.. is an IDE where you can develop with. I prefer to use PhpStorm, others
use EclipsePDT, Notepad++ or even the basic editor of windows. This is just
about syntax-highlight, code-completion and other things helping you to
develop your code.

Hope that helps :)

If somebody has been there, please write some notes ... I personally

Re: [PHP] Searching IDE.

[Simon Schick]

Hi,

There was a discussion about that on Google+ ...

IDEs mentioned there:

__Free
* Eclipse PDT (5x)
* Aptana - based on Eclipse but not using PDT for PHP (2x)
* Netbeans (12x)
* VIM (6x)
* KDevelop (1x)
* gedit (3x)

__NonFree
* Sublime Text 2 (6x) - USD $59
* PhpStorm (7x) - €94 personal, €189 commercial
* Komodo (2x) - $382
* Zend Studio - also based on Eclipse (1x) - €299

Just by a rough view over the comments, not really reading any of those :)

My personal opinion:
* Eclipse PDT
** not used since 2008
** was way to slow, specially the file-search
** missed some good PHP code support ... code-completion for classes and
it's functions was quite limited at that time

* Netbeans
** not used since 2009
** seemed as the best free IDE for PHP to me

* Zend Studio
** not used since 2008
** seemed to be Eclipse PDT with some extensions ..

* PhpStorm
** Costs a bit of money but it's really worth it.
** intelligent code-completion
** view class-structure as UML
** helper for refactoring
** supports changelists and has it's own stash
** just faster than Netbeans and Eclipse ..

That's how I used this programs. Netbeans, Eclipse PDT and PhpStorm have
way more features but this is what I used the time I tested them.

I personally would use PhpStorm if you have money - else Netbeans.

Re: [PHP] reload page without use header

[Simon Schick]

Hi, Farzan

Redirecting is something you can do in a way the user doesn't see anything
(I call them server-side redirects) and in a way the user get's informed
that the url has changed (I call them client-side redirects).

What I mean with server-side (mostly called internal redirects) is if the
user requests a page, you can do stuff with mod_rewrite (in Apache) or some
equal webserver-module to call another file than requested. The user will
not get any notice about that.

Client-side redirects can be done using the HTTP-header (see
list-of-http-status),
JavaScript (please think also about a non-js solution) and by using a HTML-Meta
tag .
In my opinion the best way to do a redirect, where the user gets noticed
about, is the HTTP-header. This can be set f.e by your webserver or by a
php-script.

Example for PHP-script:

header( "HTTP/1.1 301 Moved Permanently" );
header( "Location: http://www.new-url.com"; );

As far as I know, this is the only way to let other services (f.e. a
search-engine) know that this page has been moved permanently (or
temporarily) to another url.
That's the reason why I use the header-command (incl. setting the
HTTP-Status explicitly). If you don't set the HTTP-header, it will be added
(by PHP or your webserver). In my case, I use PHP 5.4 and nginx 1.2.1, the
header-code 302 is added if I don't set it.

May there are more ways to set redirects, but this are the one I know of.

Simon

[PHP] [PHP-DEV] SQLite - Unwanted values using group-by

[Simon Schick]

Hi, All

May you have an idea ...

Here's the full code-example:
http://viper-7.com/M5mldG

I have the following SQL command:

SELECT max(r.month+r.year*100), r.year, r.month
FROM base b LEFT JOIN remote r ON b.id = r.remote_id
GROUP BY r.remote_id

Now I expect that the first column in the results should look like a
combination of the second and third one .. so f.e. this:
array(3) { ["max(r.month+r.year*100)"]=> string(6) "201201" ["year"]=>
string(4) "2012" ["month"]=> string(2) "01" }

But instead I get this result:
array(3) { ["max(r.month+r.year*100)"]=> string(6) "201201" ["year"]=>
string(4) "2011" ["month"]=> string(2) "12" }

I tested it on Windows7 (PHP 5.4.4, SQLiteLib v3.7.7.1), where I get the
result as shown above ... and I've also tested it on a fresh installation
on LinuxArch (PHP 5.4.4 and SQLiteLib v3.7.13) - where it works as
expected! A college of mine has tested it on OSX (PHP 5.3.7 and SQLiteLib
v3.7.13) and he gets the same result as I on the windows version.
Someone of you have an idea?
Maybe had the same problem before ... what could it be?

I thought it might a problem of the SQLite-lib but both, the LinuxArch and
the OSX system, have the same SQLite version - and both, the windows and
the LinuxArch version, have the same PHP-version.

Even if the example just uses PDO, I've also tested this using the native
SQLite3 lib and I got at least the same result on Windows. Haven't tested
the other systems with the native SQLite3 lib.

Simon

Hi, Matijn

But I think you get what I mean, when I say that max() should only
point to one row, in this case the one with the latest date ;)
How is it possible to, for sure, get the data of this rows?

Re: [PHP] OT (maybe not): Drupal vs WordPress

[Simon Schick]

Hi, all

+1 for that Joomla sucks ... worked with it for a while and just got
more and more disappointed of the way they write stuff. Just look at
how complicate it is to write an extension ...

Just a bit off-toppic (since you're talking about WP vs Drupal), but I
use Wordpress for small blogs and pages where I know that people don't
have that much experience with creating webpages and so on and need
very simple systems,
and TYPO3 for more complex pages (multiple domains, multi language,
complex submenus) because the system has it's own
configuration-language (TypoScript) that this let you do so many
things, way faster than writing it down in PHP. Another good bonus is
that you can decide to hide each single checkbox, inputfield or even
selections in a selectbox in the backend for an average person
administrating the web-content.

But because of the own configuration-language the learning-curve of
TYPO3 is (in my opinion) the highest of all CMS-systems for
developers.

One thing I also really like at the TYPO3-philolsophy: If someone
finds a security-issue he should immediately get in contact with the
developers (of the extension and the TYPO3 security team) and discuss
the issue with them. They decide how critical the bug is and will do a
hard work to get the fix as soon as possible. If it is a very critical
issue (someone could gain admin-access by something) they will send
out an email that there will be a bugfix coming out at next-coming day
at 9 o'clock GMT and everyone is advised to update his TYPO3-core or
the extension. This is something I really like! To be prepared for
some critical fix and knowing that (in a perfect case) no-one should
have heard about that issue before who wants to hack my website :)

Don't know if there's some similar security-policy in other
communities than this :)

[PHP] [PHP-DEV] Separate apc-caches for each fpm-pool

[Simon Schick]

Hi, all

Not to get the bugfix https://bugs.php.net/bug.php?id=57825 too much
off-topic, I write this question in the mailinglist here:

Taking the case I have two fpm-pools on different sockets - the first
pool is responsible for www.example1.com and the second one for
www.example2.com.

If www.example1.com has 4 workers, they're all using the same
apc-cache. That's absolutely as expected. But also the workers of
www.example2.com are using this cache. In my opinion it would be nice
if the pools would have a separate cache.

I now found a solution for this: Just use more than one fpm-master
that is controlling the pools. (http://groups.drupal.org/node/198168)

Is this the way to go, or do you know of another way?
Should this be added to the APC- or fpm-documentation or is it enough
that you can find f.e. it using Google, if you need it?

Re: [PHP] Crash course

[Simon Schick]

Hi, Lester

Just try to connect to your mysqlserver using a simple php script first.

Example for MySqli:
http://www.php.net/manual/en/mysqli.construct.php#example-1625

Example for MySql:
http://www.php.net/manual/en/function.mysql-connect.php#refsect1-function.mysql-connect-examples

If you still use MySql and not MySqli to connect to your MySql-Server:
Please keep in mind, that this extension is about to die out.

I just know of mysqli and mysql that you can chosse in the
Joomla-Installation process ...
PHP itself does also have PDO. There you have to check first if the
pdo-driver for mysql is installed:
http://www.php.net/manual/en/mysqli.quickstart.prepared-statements.php
And then try to connect to your server:
http://de2.php.net/manual/en/pdo.construct.php#refsect1-pdo.construct-examples

If you're using MySqli, please try a prepared-statement as well.
http://www.php.net/manual/en/mysqli.quickstart.prepared-statements.php
I got access to a server where the administrator had mixed it up that
hard, that mysqli as PHP-extension was installed and worked quite well
excepted by the prepared-statement :D

Re: [PHP] Crash course

[Simon Schick]

Hi, Lester

I know how you feel ... I didn't want to disable E_STRICT either, but
as most of those errors come from the Joomla-Core or some extensions,
I don't have the nerves to fix code that's not mine and the developer
just says "aaa ... those E_STRICTs ... why do you even care ...".

Therefore I gave up because the developer won't fix those and I don't
want to support my own fork of those extensions.

[PHP] Who is responsible for NFD or NFC formated UTF8 text? PHP, my application or the system-administrator?

[Simon Schick]

Hi, all

Yesterday I ran into a big issue I didn't know about before:

There are many ways in UTF8 to save the same character. This applies
to all characters that can be combined of other characters. An example
for that is the German umlaut ö. In theory it can be saved simply as ö
or it can be saved as o followed by ¨.
I raised a question on stackoverflow on that and got tons of helpful
information.
http://stackoverflow.com/questions/12147410/different-utf-8-signature-for-same-diacritics-umlauts-2-binary-ways-to-write

If you don't know what NFD, NFC and those are, take the time and read
this article http://www.unicode.org/reports/tr15/ or at least take a
view at the figures 3-6.

As you read, I moved a page from a MacOSX Server to a Linux Server.
During this movement the filenames got converted from NFD to NFC.

Now my question is:
Is this a common issue?
What can I do to prevent it in the future?
Who's responsible of taking care of that?
I myself, Wordpress, the system I use, or I as the
system-administrator moving the website?

For example I don't know if Windows f.e. converts every filename to
NFC, but MacOSX (using HFS+) forces filenames to be NFD compliant.

Hi, all

I most like to use template-engines that does not allow to write
direct PHP code in the template.
This restricts you to split the logic from the displaying code.

Template-engines I know of:
* Smarty
* Twig
* FLUID
* OPT (Open Power Template)

If you want a bigger list, visit wikipedia:
http://de.wikipedia.org/wiki/Template-Engine#Template-Engines_f.C3.BCr_PHP
http://en.wikipedia.org/wiki/Template_engine_%28web%29#Comparison

What I used most is Twig. For the next project (if it has no
template-engine build in in the system I choose) I'll give OPT a try.
It looks promising ;)

Re: [PHP] Holding "datetimes" in a DB.

[Simon Schick]

Hi, Richard

I, too, tought about switching to UTC times in my database. The only reason
for me was to get prepared for globalisation.

A good article about this consideration is written at PHP Gangsta (sorry,
German only):
http://www.phpgangsta.de/die-lieben-zeitzonen

The reason, why I did not switch to UTC, was the reason, that most of the
pages I host have visitors mostly from Germany.

If you have visitors from different countries, you first have to find out
which time-zone they're in, which can be quite messy. Just watch this video
about timezones (I added a jump-node that get's you directly to the
interesting stuff):
http://www.youtube.com/watch?feature=player_detailpage&v=84aWtseb2-4#t=230s

But basically that doesn't matter that much, since you - anyways - don't
get a time from the client, so you're stuck in this problem either way ...

Each example, I can come up with, does apply to UTC saved timestamps as
well as to non-UTC based timestamps.

One consideration, if you only have to operate in one timezone, like I do,
is stuff like cron-jobs.
Since I only have Germany as main-visitor-source, I can safely configure
the server to Europe/Berlin and pull out stuff like birthday-information at
midnight.

Please do also keep in mind here, that there are not only
full-hour-timezones :)
http://en.wikipedia.org/wiki/List_of_UTC_time_offsets

But  I can't come up with a problem that you wouldn't have with a local
timezone instead of UTC ...

Simon

Hi, Karl

You're right, but restructuring, to get it the way you want, isn't be
that hard, is it? :)

$query = "DELETE FROM `__table_name__` WHERE `__date__` < NOW() -
INTERVAL 3 MONTH"

@Dusan,
Btw: What is "DELECT"? I assume it should've been "DELETE", right?

[PHP] Which function returns a correct ISO8601 date?

[Simon Schick]

Hi, all

Some days ago, I needed a date, formatted as date("c") ...

To be a bit more object-oriented, I worked with an instance of
DateTime. My first thought was: "As the documenting for date() defines
'c' as ISO8601, I can take the constant provided in the DateTime
object ... right?" ... and that was wrong.

Here's a code-example:

date("c");
// 2013-09-07T12:40:25+00:00

date(DateTime::ISO8601);
// 2013-09-07T12:40:25+

-> Take special care to the notation of the timezone.

The method date("c") actually formats a date, fitting to the format
defined in the constant DateTime::ATOM.

Are both formats (with and without colon) valid for ISO8601, or is the
documentation for the method date() wrong?

Simon

Re: [PHP] Re: Which function returns a correct ISO8601 date?

[Simon Schick]

Hi, Alessandro

Would it be worth noting somewhere, that these two implementations of
ISO8601 differ? Because I needed the DateTime::ATOM way to save the
timezone ... Even so the other one was also about ISO 8601 ...

My system is working towards a search-engine called ElasticSearch.
This one makes use of a Java method to format a date. This one is
defined here:
http://joda-time.sourceforge.net/api-release/org/joda/time/format/ISODateTimeFormat.html#dateOptionalTimeParser%28%29

The definition for a time-offset is defined like this:
offset= 'Z' | (('+' | '-') HH [':' mm [':' ss [('.' | ',') SSS]]])

Is there a format, you know of, that makes this difference (colon or
not) bullet-prove?

Simon

I suggest to read this page of the tutorial. It seems, that it solves the

Please be aware, that the ini-file is not re-read on every request, but
after a defined time.
Neither are all settings changeable in those per-user ini-files.

Read also the other pages in this chapter, they're good to keep in mind ;)

If you're now calling the script from a webserver, you called by requesting
a page on a subdomain or a top-level-domain, doesn't matter.

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.

[Simon Schick]

Hi, Elbert

I've looked through the code and found it quite tiny. I like that.

Until now I found some things that I'd like to discuss with you:

In the class App you're doing all the stuff (routing, calling the
constructor aso) in the constructor. Would it not be better to have
separate functions for that? I like the way I learned from using Java: The
constructor is only for initializing the variables you need to execute the
other functions of this class.
Of course you can have a function that then calls all those small functions
and maybe directly return the output.

I dislike the way you treat with the model .. currently it gets the
controller, the view and the app itself. If you ask me the model only needs
some configuration. I cannot come up with an idea where you'd need more
than a connection-string and some additional settings. The model has
several methods to gather the data that has been requested and gives it
back. If you'd ask me, there's no need for interaction with the app,
controller or view.

I'd like to see an option for the router like the one I've seen in symfony2
... that was quite nice .. There you can define a regexp that should match
the called url, some variables that should be extracted from that and some
default-variables. It's quite hard to explain in the short term, but take a
look at their documentation:
http://symfony.com/doc/current/book/routing.html

I'd like you to create a small workflow what your framework is doing in
which order. Your framework to me looks like this image:
http://imageshack.us/f/52/mvcoriginal.png/ But I'd rethink if this
structure would give you more flexibility:
http://betterexplained.com/wp-content/uploads/rails/mvc-rails.png

I hope you got some input here you can work with. I'd like to hear your
feedback.

Simon

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.

[Simon Schick]

Hi, Paul

I personally pretty much like the idea of auto-loaders, but that's a
personal point of view.
If you have always develop with scripts having autoloaders you'll hate to
write a *require_once* command at the beginning of all files. And what
would a dependency-injection-container be without an autoloader ;)
http://www.slideshare.net/fabpot/dependency-injection-with-php-53

If you write your code in OOP you should always have unique class-names. If
you follow this and use a good naming-convention both ways should be
usable. I prefer to use autoloaders, you maybe not and that makes code so
personalized ;) *like-it*

Re: [PHP] Swiftlet is quite possibly the smallest MVC framework you'll ever use.

[Simon Schick]

Hi, Elbert

I personally would remove the set_error_handler completely. This is a
configuration that the administrator has to handle himself. In a
development-env they want to see all errors, warnings etc, yes - even a
strict_notice. But in a production-env they dont want to show anything to
the user - just show a general error if something really heavy happened.
You can put that in the index.php but I'd wrap it in comments or remove it.

In my opinion it's a good idea to move the autoloader into the index.php.
Then you can even call your app class using the autoloader ;)

I'm just curious what exactly you want to try with the plugins ... Should
they simply be extensions or also possibilities to extend other plugins? I
also wrote my own framework 3 years ago and was more about making things
way more complex than they could be just to think about maximum flexibility
..

I pretty much also like the no-config part.

Re: [PHP] basic captcha

[Simon Schick]

Hi, all

When you ask for a captcha, I'd first ask what do you want to use it for.
If you read the first lines of Wikipedia it has been developed to differ
between a real user and a bot.

If you'd now say that you want to use it to protect spam in a formula I'd
give you the same explanation that you can find here in german (in a bit
more text): http://www.1ngo.de/web/captcha-spam.html
The author of this link says that captchas are not efficient enough and
give a new unnecessary barrier to all users. He also declaims that bots
nowadays are better than ever and can even read captchas that many humans
are not able to read.
For this reason he provides a list of extra stuff that you can use to
protect your formula against spam instead of a picture that's text should
be written in an input-field.

One of those is the honey-pot. You simply create an additional field (f.e. *
email2*) hide it for most visitors (using *css*) and ignore the comment if
there's text in here. As most of the bots cannot read css they'll fill a
valid email-address in here :) But then you also have to think about users
that have css disabled f.e. *ScreenReader*. Another disadvantage of this
issue is that you can use an auto-field-fill mechanism provided by the
browser who could fill this field ... But both cases should not be that
difficult. For the screenreder you can change the label for the field to
look like *Do not paste your email in here. Just leave it empty.* Just to
have the word email again in here ;)

Another good thing is to think about how fast this form can be submitted
when the user enters the formula for the first time. Also think about the
second time, when the user as entered some wrong values and you have to
show him a message.
If you have a formula that contains more than 5 fields it's quite unusual
that the user can submit that below 2 sec after receiving the response. You
could even add a feature by using javascript that the user cannot submit
this form or his request will be delayed for a view seconds (one or two).

If you want to know more about that, out there are plenty of plugins for
different systems where you can see what other possibilities you have. One
extension i like is the one from TYPO3. They have quite a bunch of such
things and you can give each of the checks a value. If the sum of the
values of the failing tests reaches a configured level, this
form-submission will be rejected.

Re: [PHP] pathinfo or other

[Simon Schick]

Hi, All

I do not remember where I found the list of variables that are provided if
you load PHP using Apache, nginx, IIS ...
Fact is that there's a list of variables in the CGI 1.1 definition that
should be given to a cgi script:
http://tools.ietf.org/html/rfc3875#section-4
PATH_INFO is on the list and therewith should at least be given to every
cgi-script.

As not all web-server are fully compatible to the definition or do not
support cgi 1.1 there are quite much posts where you find work-arounds for
misconfiguration web-servers.
I know about nginx that you have to add a special configuration to get the
path_info - but the example provided at the developers-page sometimes
returns a wrong value. See:
http://stackoverflow.com/questions/8265941/empty-value-to-path-info-in-nginx-returns-junk-value/

Maybe there are also some other known issues around this PATH_INFO ...
Here's a request for a portable way to receive the path-info even if it's
not provided by the web-server:
http://stackoverflow.com/questions/1884041/portable-and-safe-way-to-get-path-info

I've always tried to use something like mod_rewrite and manage all incoming
requests in an own dispatcher. That helped me a lot getting around this
problems.

Hope that this gives you more detailed information in what you need.

Re: [PHP] basic captcha

[Simon Schick]

Hei, Ashley

The php bugtracker himself uses just simple math.
Others are made by clicking on the man's name in the picture (3 shaddows of
people with names in there) ...

But I myself dislike the visitor having extra-work. Therefore I'll stick to
the honey-pot the referer check and so on.
One check I think is quite effective is something google does for
discovering spam-mail:
Discover which language this mail is written in. If it does not seem to be
a lanuage at all its most likely spam ;) But I think that's not possible
for not-so-big websites ..

Anyways: most likely it's just about filtering the 99% spam and get all
user-mails through. Nothing is more annoying as when you (as user) get the
feedback "*Go away! You're a bot.*" ;)

Re: [PHP] SimpleXML and the Single String (SOLVED)

[Simon Schick]

Hi, Jay

If you're not using the variable *$xmlCompany* somewhere else I'd try to
skip the array and just do it with this single line:
*$arrayLead[0]->Company = (string)
$xml->SignonRq->SignonTransport->CustId->SPName;*

The result should not differ from what you have now.

Re: [PHP] How do I enable more useful PHP error logging?

[Simon Schick]

Hi, Daevid

What you could do to have it quick is to install the plugin xdebug.

Here you can (as described in the documentation linked here) enable to get
some extra information for a E_* message from php.
http://xdebug.org/docs/stack_trace

I would not do that on a live-system where you have 30k v/s without
changing the default configuration as there are several options that would
dramatically slow down the system.
But if you're configuring this properly I think you'll get the best
information without changing the php-code itself.

Re: [PHP] Website preview script

Hi, Ashley

The question is what this function does ;)
I think it really takes a screenshot of the server - whatever is shown
there right now. But how to get a browser running there in full-screen?

I came around that post for a couple of weeks ago and thought it could be
useful for someone here:

Re: [PHP] SESSION var and Objects problem

[Simon Schick]

Hi, Jim

To avoid this kind of problem it would also help to provide an
autoloader-function as PHP then tries to load the class-definition by this
autoloader ;)
Using that you'd bind yourself to have a pretty good system for php-classes
and you'd avoid having problems like that.

I'd in fact have never thought about a solution like that - but that may
comes from the fact that I always use auto-loader-scripts ;)

One additional info:
I had some problems putting an instance of *SimpleXmlElement *into the
session ... The only valuable info I found was this error:
*Fatal error: Exception thrown without a stack frame in Unknown on line 0*

Here's the solution and description why:

Re: [PHP] Function mktime() documentation question

[Simon Schick]

Hi, All

To bring a work-around into this discussion I myself would not see it
as a good way to do it like that - even if the documentation provides
some information around that.
Here's what I have done in all new projects I worked with time-calculation:

@Tedd: Lets pick up your first example and work with the
DateTime-Object instead:

$date = new DateTime($year . '-' . $current_month . '-1');
$date->add( new DateInterval( 'P1M' ) ); // Add a period of 1 month to
the date-instance (haven't tried that with the 30th of Jan ... would
be kind-of interesting)

$days_in_current_month = $date->format('j'); // Get the date of the month

As this does not solve the problem (as we still should update the
documentation or the code if it does not match) it's not a solution,
but a suggestion to coding-style at all.
It seems a bit cleaner to me as you don't have to worry about the 13th
month, time-zones or other things that can be difficult to calculate
yourself.

I would next try curl as php-extension.
If that is working well, and you need it definitely with file() I'd use

Can you give us some more information?

How is php called in your apache-configuration? (f)cgi, module or somehow else?
You said that the configuration should be the same ... can you

Hi, Lester

You're talking about some kind of "installer" ... What exactly is it?
And what exactly do you mean with "ZEND does not seem to log ..."?
Apache, PHP or something that's controlling both?
And the more interesting question as you're only talking about ZEND
... in which log-file have you found the notice? I guess it's the
log-file of Apache ...
I guess you have already tried to set Apache and PHP to the lowest
possible error-level ...

I searched up the inet and came across totally different solutions ...

Things that I found you can try:
* Replace the index.php ... Some people reported that this error was
caused by an endless-loop in their php-script
* Disable all php-modules that are not really needed (f.e. APC or eAccelerator)
* Disable all superfluous apache-modules (you should have done that
anyways, but let's try to put it to a minimum)

Here's also one tutorial how to get more information out of the
apache-process. Haven't tried that and can therefore just give the
hint to test it once.
http://stackoverflow.com/questions/7745578/notice-child-pid-3580-exit-signal-segmentation-fault-11-in-apache-error-l

Hope you can get some more details ...

Hi, Lester

I suggest that all done with this variable before is not of interest ...
Assuming this, I'd say the following:

> $secondsGap[] = array($gap[0] * 60, $gap[1] * 60);
Implicit initializing of an array that has the following structure:
array( array(int, int) );

> if( isset($secondsGap[1]) ) {
Trying to get the second element .. which will never happen if you
haven't added an element before the snipped you pasted here.

>$gapName = $secondsGap[0]."to".$secondsGap[1];
> } else {
>$gapName = $secondsGap[0];
> }
[some-code]

I'm quite unsure what you want to do here. If you'd update the first
line as following it would always trigger the first condition:
$secondsGap = array($gap[0] * 60, $gap[1] * 60);

Hi,

I got a rough overview of the conversation in the bug-tracker ...

You were always talking about a tool you used to test the
gzip-compression ... but why not test it natively?
Using Firefox (with the extension Firebug) or Safari / Chrome for
example you can easily view the respond-header from the server and get
more info out of that.
Just press F12, click on the network-tab, select your request and
search in the response-header for "Content-Encoding: ..."

I would write my own small php-test-script where you just output some
text. Then you're sure that not other code is doing something strange.

Another possible problem: Is the extension zlib enabled at all? The
documentation says that it's disabled by default ...

Hi, Robert

Does not seem like a bug to me ...

What you should do to get the expected result:
Unset the variable after you don't need this reference any longer.

Hi, Arno

Requesting that will at least require a major-release (f.e. PHP 6.0)
... but I would rather request to add a notice or warning to the
documentation of references to remind stuff like that.
http://www.php.net/manual/en/language.references.php
I think this is stuff more people will stumble over ...

Re: [PHP] including PHP code from another server..

[Simon Schick]

Hi, Rene

I just want to say the same ... whatever you're trying to do here - it
will end up in a major security-isse that (I think) you won't fix that
soon as someone has hacked your server.

That sounds like you don't wanna pay 10$ per month for a good
multiple-domain-hosting solution.
If you're searching for something cheap for multi-domains, take a look
at providers like DreamHost or something similar.

I don't know if this is written somewhere in the php-manual, but I

Hi, Simon

Sorry for this out-of-context post - but just to answer to Simon's question:

One way of implementing Singleton in PHP is written down in the php-manual:
http://www.php.net/manual/en/language.oop5.patterns.php
I personally would also declare __clone() and __wakeup() as private,
but that's something personal :)

If you have many places where you'd like to use the Singleton-pattern
you may now think of having one class where you define the pattern
itself and extending other classes from that ... But that does not
seem the good way to me because this classes are not related at all,
in case of content.
Other frameworks are using interfaces but they have to write the code
for the implementation over and over again.

Here's where traids make the most sense to me:
