Hi Kristina,

have you tried the lates cvs snap? I know there was some problems with
apache2 and mod_rewrite maybe it is solve in CVS.

[PHP] php5 call by refference

[Georgi Ivanov]

Hi,
AFAIK, in PHP5 one can't call function with function parameters .
The error is that you only can pass variables by reference.
foo(strlen('aaa'),strlen(''));

Is there some sort of workaround ?

Re: [PHP] mod_rewrite and include paths

[Marcus Bointon]

I found the source of my mod_rewrite problems. I was doing everything  
right to start with - The odd behaviour was due to a PHP bug (http:// 
bugs.php.net/bug.php?id=35059) that's fixed in 4.4.2-dev and 5.1.0RC7- 
dev (I'd assume 5.0.x as well). Recompiling with a new checkout works  
fine.

Georgi,

You should assign the output of the functions to variables before the
call and use those variables as the parameters.

which means that you can't use a function call as the argument to a
function that required the argument to be passed by reference, if the
argument is not passed by reference then you can use a function call as
the argument directly.

apart from, atleast,  func_get_args() which cannot be used directly as a
function argument for some reason I don't fully understand (has to do
with engine internals I believe)

You can call functions like that without problems UNLESS the function  
is expecting values by reference, i.e. results are passed back  
through the parameters. If you supply a function result, then you may  
as well not be calling the function as you'll never be able to get a  
result back from it, hence the error message. e.g.


function foo(&$a, $b) {
$a = $a.$b;
}

If you call this as you asked, where would the result go?


Is there some sort of workaround ?


As was suggested, put your values in variables before calling the  
function, though the code example you posted suggests you're trying  
to do something odd.

Strange as it may seem, you'll probably find that this is the fastest  
method:


'first part of string '.(($a==$b)?$c:$d).' rest of string'

I benchmarked this a while ago and was surprised to find that  
multiple concats with single quotes are significantly faster than

I thought it was a good idea for a while... One major irritation with  
it is that with standard error reporting you can't tell where a  
missing class can't be found from (it is reported as having come from  
your __autoload function). You need a stack trace to figure out where  
the original problem occurred - xdebug works a treat (but it won't  
mix with APC).

First of all, the problem with this arises if your function foo is
defined as

  function foo(&$a,&$b) { ... }

There is no problem if a and b are not reference parameters.
So think a second about this: You tell in the definition of foo that you
want to write to the position where a and b are stored. But by calling
the funtion with strlen() you don't have a position in user space
because the results of strlen() are just values which haven't been
explicitly stored.

Now you can decide if you don't write to your parameters a and b. Then
there is no need for call by reference! It is not true that PHP copies
the value and that you save memory by using references! The values of
call-by-value parameters are copied if and only if you WRITE to them!
The Zend Engine 2 is highly optimized for this.

If you want to write to a and/or b then you must supply a storage
container (also called variable *g*). Simplest way of supplying a
temporary container:

  foo($t1=strlen('aaa'),$t2=strlen(''));

Have Fun!

[PHP] Re: Deployment and maintenance of php software

[Oliver Grätz]

Andy Pieters schrieb:

First of all something about packages: PEAR is coming up with their own
format ".phar" for this. These are tar archives that may contain an
additional PHP script that is executed when unpacking the archive. This
gives you all the possibilities of other package management systems.

If you decide to go for standard package formats: I can't tell you
anything about .rpm but I know that it isn't too difficult to build .deb
packages. There are good howtos for the debian format.

As another approach: How about using Subversion? PHP developers have one
advantage: They don't have to compile their code before deployment. So
in other words: Deployment is somehow very similar to just getting the
source code. Subversion on Apache allows for easy access control. You
cann create a deployment branch or even different branches for each of
your customers. After you have created some new features in your project
you can simply merge the changes to your braches. All the client has to
do to fetch this update is one single "svn up"!

[PHP] Sorting users geographically...

[Tony Di Croce]

I'm helping a friend of mine build a matchmaking website, and we have a
doozy of a problem to solve:

What I need to do is two fold:

#1 Collect whatever geographical information I need from each user to enable
#2
#2 Be able to run query's to find people NEAR (geographically) another
person.

Does anyone know of any commercial or free implementations of this? Is it
primarily a database problem or is their some way (computationally) to
compute the probable proximity of two zip codes?

Hopefully someone responds to this with a Pear package that does exactly
what I need! :) If that can't happen, then I'd appreciate any options you
can think of.

Hi Tony,

I would think the first step would be to find a web service or dataset
to convert a zip code to longitude/latitude.

The formula for calculating distances from long/lat is available here:

That's like using a bulldozer to tidy your living room. Why not use the

$outputStr =

Try measuring the difference between the various methods over a

yes it is actually - everything is in the eye of the beholder.
it just so happens that we often have consensus ;-)

with regard to the bulldozer metaphor - true that using sprintf() is
such a simple case may be excessive BUT I was merely introducing the OP to
something new (possibly) - anyone asking such 'simple' questions is
not at a stage that this kind of efficiency is an issue (i.e. give
them 'whats possible' before telling them 'whats best')

the sprintf() example leaves lots of room for creativity and
code reuse (even by relative newcomers) or aleast the possiblity of
writing more managable code Chris Boget liked it anyway :-)


PS - Robert Cummings, I totally agree with your general comments on
internals@ regarding migration/irritation/etc btw. and if I didn't
spend so much time on 'fixing' my working code I might have had time
to take a proper look at your InterJinn project - more's the pity
that I haven't been able to so far :-/

[PHP] Uploading more than one file

[Shaun]

Hi,

I have a form on my page that has many file input fields:


   File A:
   
  

   File B:
   
  
...

I have looked on php.net and there is a way to upload an array of files but 
one would need to make the name of all the input fields are the same. I need 
to make sure that the file uploaded is correct by comparing the file name to 
the value requried by the form field name. Is there a way around this?

Thanks for your help.

There is a class called zipLocator.  I think I found it at 
phpclasses.org.  It uses a large zipcode database, which can be 
downloaded for free (the address is in the class).

This will return all zipcodes within a specified distance from the 
target zipcode (10 mi, 50 mi, etc.).

If you can't find it, contact me offline.

I can verify $_REQUEST is correct for me, and I'm sure it's correct for 
him too, since he gets "Cookie NOT set."  The second if statement 
requires $_REQUEST['page'] to be 1 to even get to that line.  If 
$_REQUEST['page'] is not set, he should get no output at all.


I've been looking through the comments in the manual, and several people 
mention privacy policies creating a problem in IE.  My problem is none 
of this can be duplicated on my machine (or any other so far), and this 
customer is in Florida and I'm in Virginia.  I've also never seen in 
other applications that a privacy policy truly needed to be sent to 
allow a cookie to be set, and apparently the web site manager settings 
(where you explicitly allow or block cookies from certain domains) 
override all privacy settings in IE anyways.  So that seems like a dead end.

But I sure would like to see the URL once he has clicked it. Have you tried

there is likely to be a clue.

On privacy policies in IE (can he try another browser?) what is his setting?

What about third party software? Norton for example has cookie
features that will totally over-ride any IE setting with regards to
blocking them, etc. It's not the only one.

Hi,

I just installed the latest available snap, and now I'm seeing a zend

I think there are two things worth noting:
1. /home/sys/Zend is a separate installation of Zend ... does this
need to be updated as well?
2. this segfault is only happening for one script, as far as we know. 
Is there anything I should look for in this script to narrow things
down?

[PHP] Decision table/business rule parser?

[Geoff - Creative Living]

Hi

Does anyone know of an open source or commercial php library for parsing
decision tables? Or failing that, a more general business rules parser?
I can't find anything on the usual php script sites.

Unless I'm missing something, this seems to be a gap - in the Java world
there is a wide choice of native solutions.

If you named the fields like this:
 
 
 
 

Then did something like (or whatever):

 $error) {
echo $key."";
echo $_FILES["files"]["tmp_name"][$key]."";
echo $_FILES["files"]["name"][$key]."";
}
?>

Would that do what you need to get done?

After disabling Zend in php.ini, I get:

#0  0xb7df5ee9 in yy_push_state (new_state=1)
at Zend/zend_language_scanner.c:5831
5831yy_start_stack[yy_start_stack_ptr++] = YY_START;
(gdb) bt full
#0  0xb7df5ee9 in yy_push_state (new_state=1)
at Zend/zend_language_scanner.c:5831
new_size = Variable "new_size" is not available.
(gdb)

php is, of course, still installing its own zend extension.  But all
of the lines pertaining to Zend were indeed removed from php.ini.

The answer is probably in your php.ini.  Look into whether you are 
running in safe mode or not, and if you are whether you have your 
program in the safe_mode_exec_dir or not.  Also check disable_functions 
to see if any of the ones you are having trouble with are listed.

There are two ways for retrieving data. The first you have seen is the
tag form, but obviously that's a problem when the data goes into a tag
:) For this there is the embed form (a simple example follows but data
can be retrieved from modules/components in the same way):



Embeds can be nested as can tags. Additionally, embeds can be used
outside of tags, they're just most convenient there.

With respect to forms, InterJinn supplies a form engine that does most
of the rendering, and which can be assigned to slices. Then output is as
simple as:





Or if you want to customize the form field but still have the internal
validation semantics:





As long as you use the internal form open and close semantics, and use
the same name given to the field internally, you can render the field as
you would in HTML. I generally don't use that method, since I like to
use configuration arrays or properties to determine how the fields look.
Either way, the engine is very flexible and gives the developer lots of
choice in how they go about the display and how much control they give
the designer.

Unfortunately the documentation for the form engine isn't currently up
to date, since I've added less cumbersome techniques for creating forms
than what it currently documents. The faster techniques don't require
working with the objects but rather just define configuration arrays
that then generate everything else.

Let me know if you have any other questions.

Cheers,
Rob.

Start with something like cURL or Snoopy, to make life a little

I won't disagree, but I'd say being in the habit of writing semi-optimal
code in the fist place, will save you needing to learn new habits later
when you do work on a *seriously* busy site :) I didn't argue for ''
versus "", but sprintf() is a cycle pig in comparison to either. not
only that, but since it's not a keyword, it incurs stack overhead.

Cheers,

True, coming from a C background I can attest to my love for the *printf
series of functions. In fact, 6 years ago I might have actually liked
Java more if they had bothered to add it (I've heard it's been added
since).

*lol* Might be good till I clean the docs up. Also I've been adding a
flurry of stuff lately to support better inclusion of external resources
like JavaScript. I want clean including of javascript modules within
templates and modules such that requesting the resource never includes
it twice and so that I have the same replaceable modularity that exists
in InterJinn. Also I want to have dependencies managed internally rather
than having to think about it myself. I guess I'm making a mini
JavaScript InterJinn lib *lol*. This will tie in nicely with my work to
bring in almost transparent XmlHttpRequest functionality.

[PHP] Regex for balanced brackets?

[Jeffrey Sambells]

I came across this method of matching brackets with regex in .NET

http://puzzleware.net/blogs/archive/2005/08/13/22.aspx

but I am wondering if it is possible to do the same in PHP?

I've tried it a bit but I can't seem to get it to work properly. I'm  
just wondering if I am doing something wrong or if it is just not  
possible.


Thanks.

here is the code I was playing with:

There's a wide range of Java solutions:

http://www.manageability.org/blog/stuff/rule_engines/view

Most of them are over-specified for our relatively modest requirements.
Plus, I've never really looked into the practicality of using Java
libraries with Php 4. The only practical option I've found is this
project:

http://sourceforge.net/project/showfiles.php?group_id=117793

... but it's only got a couple of developers and I'm wary of betting my
business on a library like this. Do you know a better way?

With our modest needs, I'd much prefer to find a native solution, (if
such a thing exists) rather than add a layer of complexity and potential
unreliability by inter-operating with the Java VM.

Re: [PHP] Decision table/business rule parser?

[Mike Smith]

I'm not aware of any. I am kind of developing my own for my current
Materials System. We purchase aluminum and glass from multiple
suppliers. The costing of those materials can vary supplier to
supplier. I'm working on an interface that will basically let the
Material dept work with a Part Profile (taking specific
characteristics specific to a certain set of parts) and create a
formula (by supplier) and whatever grouping from the part profile
(e.g. the Glass profile has a combo item called Thickness with several
options 3MM, 4MM, 5MM... That's probably more than you wanted to know.
All that to say, if your requirements are modest it may be worth it to
"roll your own".

With jBPM I "hope" I'll be able to change "routing"/approval of
electronic documents more easily than it is currently.

Good luck,

[PHP] php 5.1rc6, oci8, and ldap

[Robert Hopson]

Greetings,

I am trying to compile PHP 5.1RC6 with support for both ldap and the
oci8 extension (using the Oracle Instant Client).  To get this working
under PHP4, I had to modify the Apache (1.3) environment like so:

   LD_LIBRARY_PATH="/usr/lib:${ORACLE_HOME}"
   LD_PRELOAD="libldap.so.2:libclntsh.so.10.1"

Given those settings (and a valid ORACLE_HOME location), the following
code works on a PHP4 build:

   $res = ldap_connect("ldaps://$ldapserver");
   ldap_bind($res, $bindrdn, $bindpw);

But under PHP5, running that code gives the error:

   Warning: ldap_bind() [function.ldap-bind]: Unable to bind to server: Out
   of memory in  on line 3

The oci8 library functions correctly.  Does anyone have a working setup
for this, or any thoughts on what else I might try?

Thanks,

-Robert

[PHP] forking problem and logging off - solved

[matt VanDeWalle]

I have fixed my prier problem of my script crashing down whenever i logged 
out of the shell, I got a bright idea, (one of the few it seems i'm having 
lately :p )
I found out that there is a "nohup" command ..i guess i knew there was but 
i had forgotten that until today.  I put this in a script now to run my 
chat now with nohup, something like this

/* my script to start server */
#!/usr/bin/bash
nohup ./server.php &

of course i have to be in the right directory to do this but it works and 
finally, i can log off of my account without the server going down yay!

[PHP] username format when binding to Active Directory?

[Bing Du]

Hello,

The following script returns 'LDAP bind failed...'.

";

$ldaprdn = "[EMAIL PROTECTED]";
$ldappass = "jsmithpass";

$ds=ldap_connect("ad.dept.some.edu");

if ($ds) {
   echo "Binding ...";
   $r=ldap_bind($ds, $ldaprdn, $ldappass);

   if ($r) {
   echo "LDAP bind successful...";
   } else {
   echo "LDAP bind failed...";
   }
} else {
 echo "LDAP connection failed...";
   }

?>

If I change $ldaprdn to be "CN=John 
Smith,OU=Users,OU=DEPT,DC=some,DC=edu", then bind returns 'LDAP bind 
successful...'.


However AD supports username to be in [EMAIL PROTECTED] format 
because querying from the command line works:


% ldapsearch -h ad.dept.some.edu -s sub -b "dc=dept,dc=some,dc=edu" -x 
-D [EMAIL PROTECTED] -W "samaccountname=jsmith"


Our AD only allows authenicated bindings.  We don't know user's DN 
before binding.  So anybody know how to make PHP allow 
$ldaprdn="[EMAIL PROTECTED]"?


Thanks in advance,

[PHP] Including classes

[Philip Thompson]

Hi all.

Here's what's going on. I have a page which calls itself in a .  
On this page, I include two classes from other file I've created. On  
load, the page reads the class stuff just fine. If I submit the form  
(call the page again), then the class doesn't like to show any results.







   
   





Any thoughts on why the class is not working after the submit? I have  
tried using require_once ("myclass1.php");, but that  
does not work either. Any suggestions would be greatly appreciated!


Thanks in advance.

I guess you missed the custom tag post I made before:





"project" is an arbitrary name generally chosen to reflect a project.
For different projects I usually assign unique tag spaces for any given
project. Often used tags that I share between projects I usually assign
a tag space name of "common". And tags that come packaged with interjinn
are assigned the "jinn" tag space name.

There's other ways too. InterJinn supports if/elseif/else tags for
display logic (such as optional content based on some status). The
custom tag just happens to be very concise and clear which is generally
how I tend to make my templates :)

The templating engine isn't just limited to these types of tags, custom
compilers can choose to extend the base tag or embed classes, or they
can do whatever they want to the content. The tag system just happens to
be what I tied in most closely with the application engine.

Cheers,
Rob.

It appears that the data "op=View" is embedded in the html data.  This seems 
strange, because the PHP programmer is the one who needs to set this value, 
not the page designer.

Also, the jinn:getValue seems a lot like programming -- The "id" value must 
come from a database, based on who is currently logged in.  I assume it can 
be done, but seems like these queries would get rather complex, as well as 
redundant. Seems like you are changing from programming in PHP to 
programming in this new jinn language.

I am interested in how this works, but am skeptical.

You asked for a sample of how to do dynamic link parameters. Dynamic
parameters can come from many sources (_GET, _POST, component, foreach,
etc). I gave you an example of one parameter being dynamic, the first I
left as static since perhaps the page itself determines the value.
InterJinn's TemplateJinn employes a data "pull" philosophy. Component
developers make available data and templates consume it (reverse of
smart which forces developers to import templates and populate the
template). Generally for simplicity I just set member vars on the
component object. But vars can be set anywhere depending on what is
agreed upon by the developer and the designer. The render tag bypasses
lower level data retrieval and just requests a chunk of output by
selector name.

Decisions are made in any design. Since InterJinn employs data pull
mechanisms, and modules/components are created to be consumed by
templates, such that designers can import any module they want (and as
many) and just layout the data how they please, it was imperative that
one module's data not stomp on another module's data. In this way the
{getValue} embed drills down into the data structures of an existing
array or object. is this programming? Not really, it's no more
programming than you opening up a dictionary, jumping to the A section,
and then looking for Apple. This is data retrieval.

>  Seems like you are changing from programming in PHP to 
> programming in this new jinn language.

TemplateJinn employes very few logic techniques. Business logic is
expected to occur in the modules/components/compilers. I guess in the
above example I could have used the following instead:



But this presumes the id comes from a module. I just showed an example
of retrieving the ID from the GET parameters to the current page
*shrug*. Also, it is true that TemplateJinn introduces new syntax, I
never said it didn't, but I am happy to pay the small price of some new
syntax to increase the readability and brevity of my templates.

> The "id" value must come from a database, based on who is
> currently logged in.

As pointed out in a previous post, a developer can wrap such low level
data requests in custom tags. if I want cross site template access to
the currently logged in user's ID then I'd add a custom tag to do the
following:



> I am interested in how this works, but am skeptical.

No problem, the "programming in X template" instead of "programming in
PHP" objection is raised often. I've given previous arguments about the
merits of templates and concise data retrieval, display logic versus
business logic, and meta tags versus traditional tags. Everything done
in TemplateJinn can be done in PHP, absolutely since templates compile
to PHP pages, but templates provide a layer between the soup of PHP
necessary to accomplish that, and the designer. Even as a developer I
don't want to engage in the soup necessary to accomplish everything
TemplateJinn now does for me -- unfortunately I maintain some sites that
do employ the soup system.

Cheers,
Rob.

Re: [PHP] Regex for balanced brackets?

[David Tulloh]

I think you are doing it wrong, though reading other people's regex 
easily is a skill I lack.

It is however very possible.

The php manual has a section on recursive regex where it explains how to 
solve the bracket problem.

http://php.net/manual/en/reference.pcre.pattern.syntax.php#regexp.reference.recursive
I think of recursive regex as creating goto loops, with all the power 
and problems that come with it.


You will also have to enable the multiline flag for your test data.

This means basically that the header files (*.h) where found but
none of the libraries were found.

You're compile path looks awkward to me.

what does your ./configure line look like?

   How so?  /usr/local/src/apache is simply a folder where I have all 
apache related sources dumped and compiled prior to installation.  So 
naturally PHP's source becomes /usr/local/src/apache/php-5.0.5

   This same configure line compiles PHP4.4.1 just fine.  It's long:

   ./configure --sysconfdir=/etc/httpd/conf --mandir=/usr/share/man

RE: [PHP] security question... "man in the middle attacks"

[bruce]

your questions are on point...

if you're going to really talk about doing transactions... it appears to me
that you really need to solve this. www.passmarksecurity.com claims to have
solved this.. although i'm not sure i agree with them.. for one, i can't
find a thorough independent analysis, for two, from what i can tell... they
rely on the server app getting information from the browser. their approach
appears to depend on their belief that the intermediary (fake) app can't be
in the middle, therefore they'll only get valid information from the 'real'
browser...

as far as i can tell, their solution is to look at certain information (mac
address/headers/etc...) that they're inclined to believe can't be
altered/spoofed. i'm not buying it

as far as i can tell... you essentially need multiple information streams on
the client(browser) machine coming from the server... in actuality, i can
envision the following...



   master server  <> customer client
/  \
   /\
  biz server <---> customer browser

the customer and the biz server talk to each other
the customer client and master server talk to each other
the customer client and browser are on the same machine

 the idea would be for the client app to be abel to 'get/see' the url that
the biz server app is sending for return requests. the client app would then
go back to the master server to 'determine' if the url/ip address is corect
for the given site. this can be accomplished fairly quickly by polling
random dns servers at the master level.

if the majority of the polled dns servers return the same address as the one
from the biz server, we can assume that the biz server is giving the correct
url/ip addresses.. this could be done for every request.

this kind of approach would be pretty difficult to corrupt, unless the
client app where somehow mangled/forged. you could determine if the client
was ever screwed with by using an SMS type of system via the cell phone...

Subject: RE: [PHP] security question... "man in the middle attacks"


'man in the middle' relates to any interception/redirection and I see I was
looking at it more as a hacker posing as the user interacting with a
legitmate site rather than the user interacting with a bogus site.   Two
sides to a similar coin.


real site <> bogus user - bogus site <-> real user


the session ID issue I was talking about helps prevent a bogus user from
posing as a legitimate one because only the real-site and the real-user
should know the session ID being used but then again, it could be
intercepted.  I think there's more to it than I'm explaining, but it's not
coming to me right now.  My apologies for not being more specific.

Definitely check out Chris Shiflett's site: http://shiflett.org/ (I got
un-lazy for a moment to look it up).. he might have something in there
somewhere.

I think what you're talking about is going to be kind of tricky because more
so than other security issues, this issue seems more susceptible to
measure/countermeasure type things.   You could use a secure connection, but
what happens if the hacker gets a certificate for their bogus site?  What
happens if they mask the URL so it appears to be coming from the legitmate
site?

I'm wondering how often the scenario you're talking about will come into
play though.  Seems that unless someone hacks your site and puts in some
bogus URLs that drag your legit users away from your legit site, the only
way someone's going to get lured into this situation is if someone is
posting bogus URLs somewhere else.. like on online forums or something
saying "Come see Bruce's website!" and going to a totally different URL
posing as yours.  In which case you can really only rely on your user's
intelligence to NOT fall for it.

Anyway, just some things to ponder while you find a "real" answer. :)  I
have some experience with security issues, but wouldn't necessarily call
myself an 'expert'.  Working on it though.

i'm not sure i see how this would affect a man in the middle attack...

a man in the middle attack, for the purpose of this thread is the insertion
of a clone/fake web app between the user's browaser and the original web
site...

i'm looking for ways/solutions that will prevent a fake/clone site from
redirecting the user, or intercepting the user/initial site traffic...

  original  fake user
site   <--->site   <->  browser

in this case a fake site could look like the original site, intercepting the
communication between the original/user. how can it be detected, can it
really be prevented?

as far as i can tell, what ever the original might send to the user's
browser, can simply be intercepted by the
