Re: [PHP] MySQL Newbie ? -Help!

[Jason Brooke]

one simple way would be to make a duplicate, empty table and then do:

insert into newtable select distinct * from oldtable


then try adding a uniqueness constraint if you don't want duplicates in the
future

Go to http://www.mysql.com
You'll see a 'Search' field near the top left. Type the string:
Lost connection to MySQL

..into it. It brings up about 50 results

Re: [PHP] logging page views, which method is better????

[Jason Brooke]

I take advantage of a handy feature of apache that allows log data to be
piped to another program instead of written to a file - and pipe it's log
data directly to stdin of a small C program which does a tiny bit of parsing
before putting it into mysql.

Before I did it in C, I was just using a Php script - which, incidentally,
was fine - I only redid it in C in the interests of saving a bit of cpu and
memory on the heavily worked servers it's being utilised on.

The beauty of this is that your data is always up to date, you can log any
number of servers to the one central database via tcp (or multiple databases
if you prefer) and you don't have to manage (potentially) unwieldy logfiles.
Also, if at a later date you wanted to go back to using a regular text-file
parser for your stats, there'd be nothing stopping you from dumping out the
database contents back into the Apache log format again.

So far the only negative I can see is that if mysql is down, you lose your
log data for the duration of the downtime. Not a big negative to me, since I
like to make sure mysql is running at least as often as the webserver is.

[PHP] readfile and Location headers in php 4.0.4 and 4.0.4pl1

[Jason Brooke]

Is anyone else having trouble in 4.0.4 and 4.0.4pl1 with readfile when the
argument is a http request to a script that sends a location header?

eg:

server1 - test.php

http://server2/location.php"); ?>

server2 - location.php

http://some.other.url); ?>

Both Php 4.0.4 and 4.0.4pl1 return:

Warning: readfile("http://server2/location.php") - Success in
/path/to/test.php on line 1

I've got a box that still has 4.0.2 on it and this works fine on it.

Re: [PHP] FW: Cookies, Dammit!

The thing that usually intrigues me is why people design their application
so that it needs to redirect to another page just so that they can attempt
to read the cookie back. Do they not already have the value of the cookie in
order to be able to set it? Why attempt to read it back straight away?

Any reason you don't include the contents of /index.htm into
/ministe1/index.htm with the appropriate welcome message instead of
redirecting, or even pass the site name in the query string of the Location:
URL if you're not wanting to rely on http_referer?

Re: [PHP] FW: Cookies, Dammit!

[Jason Brooke]

I hope you don't mind me nagging on this ;) but what do you mean by having
to echo changes into the /minisite directories?

What I meant was, from minisite45/index.htm, include() the same content
include file you use in /index.htm. I'm not seeing why the
/minisite/index.htm pages need to change at all? The only thing that
would change is the content of the include()'d file that /index.htm, and the
minisite/index.htm include.


/index.htm










main_include.inc:






/minisite45/index.htm

It's probably less of a security risk when utilised via the cgi actually, at
least when using Apache as the webserver because you can use suExec to cause
it to run under the script owner's uid instead of Apache's. I've often
considered switching vhosts over to the cgi version instead of module for this
very reason.

Hi Tyler - did you check the date functions in the manual?

date() with the 'n' format let's you grab the month's ordinal from a unix

$next_mon = date("n", mktime(0,0,0,date("m")+1));

Re: [PHP] (HELP) Reading a file sent through HTTP

What request method is it then? I only know of HEAD and PUT other than GET

make a script that receives their request, and write

I don't think socket functions will help you read it anyway, unless you

The former is being treated as a string, the latter is a double/float
You probably don't need to format them when making the comparison. Just try:

Instant fix - include "footer.inc"; exit;

Better fix: decide your logical layout before you proceed and arrange if/else
blocks accordingly so you don't need to terminate the script to avoid showing a
page's contents.

ie: have your single template shell which includes a particular content
container if your code allows. here's one way

http://your.domain/your/script?include=../../../../../../../../some/secret/file
*/
unset($include); // will do for the purpose of this example

if ($something)
$include = "this_particular_content.inc";
else if ($something_else)
$include = "this_other_content.inc";

include "your_header.inc";

include $include;

include "footer.inc";
?>

Recently I have had to defend the use of PHP in light of a number of
screw-ups with the mail function in 4.0+.  It seems that some email
addresses will simply "not work" with mail.  I have been shopping around
for a smtp direct class ( http://www.zend.com/codex.php?id=347
 &single=1 ) looks pretty
good to me and was wondering if anyone has any experiences, shortcuts
etc. to this kind of problem with mail.

He already stated that the same code worked with a previous version. He also
made it clear that he was using Win32/SMTP. We all know it will probably
work on a Unix box with sendmail or similar because so many of us use it on
a daily basis with no such problem - that won't help his situation.

I think probing the guy a bit on the premise that he might be mistakenly
loking at Php as the problem is fair enough, but beginning an inquisition
certainly isn't warranted   ;)

Use fsockopen to send the data:

if ($sp = fsockopen($host, $port)) {

  fputs($sp,"Host: $host\n");
  fputs($sp,"Content-type: application/x-www-form-urlencoded\n");

Probably because you weren't following the SSL protocol

I made a little C program to do this a couple of years ago. I'm not very
good at C but if you want the source anyway, just email me.

Incidentally, the number of bytes transferred to the client is available in
the Apache logging - check the Apache manual for the format specifier under
the LogFormat directive.

Re: [PHP] Using mcrypt in PHP

hopefully someone who knows what they're doing can reply to you, but in the
meantime this should get you going - it works for me:

$td = mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_ECB,
"/usr/lib/mcrypt-modes");
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, "your key string here", $iv);

then just use mdecrypt_generic($td, $data) and mcrypt_generic($td, $data)
where $data is your string to encrypt

move it out of the document tree if you don't want it executed via http, and

The ability to 'speak ssl' instead of plain text

You should probably use the curl functions to do your post via SSL, or some
other tools if using the curl funcs isn't suitable for you. Incidentally,
you're doing a GET anyway when you say that the server requires a post.

if you're using apache, something along the lines of the following untested

I didn't think of that

I just did a test on my own server and used
readfile("http:///cgi-bin/test";) where test just prints
getenv("REMOTE_ADDR") and it prints the ip address of eth0, so you'd be able
to do it this way - but I don't think using readfile() is as nice as
virtual() in this case because readfile() performs another literal http
request back to the server causing the use of another httpd process I think,
whereas virtual() probably doesn't

Another way you might be able to do it is find an environment variable that
is only present when the cgi's are executed by the virtual() call, then use
the apache SetEnvIf directive combined with

9.4 HEAD

   The HEAD method is identical to GET except that the server MUST NOT
   return a message-body in the response. The metainformation contained
   in the HTTP headers in response to a HEAD request SHOULD be identical
   to the information sent in response to a GET request. This method can
   be used for obtaining metainformation about the entity implied by the
   request without transferring the entity-body itself. This method is
   often used for testing hypertext links for validity, accessibility,
   and recent modification.

   The response to a HEAD request MAY be cacheable in the sense that the
   information contained in the response MAY be used to update a
   previously cached entity from that resource. If the new field values
   indicate that the cached entity differs from the current entity (as
   would be indicated by a change in Content-Length, Content-MD5, ETag
   or Last-Modified), then the cache MUST treat the cache entry as
   stale.

You go to the online manual, browse to the Filesystem Functions section and

There possibly is, depending on your operating system (which you didn't
mention) but you should probably consider doing it a different way - create
a database table which contains jobs to do and have the apache side of php
insert entries into that table, then have your root php script (running at
intervals determined by you), check that table and perform the tasks set in
the database table.

If any of the commands you execute from the root php script take
user-submitted data from the database and pass it to the command line, be
sure to check it for naughty stuff - there's sections in the online php
manual about security, and passing data to the command line

Yes, you can get it from the webserver environment - there's a section in
the Php manual about this here:
http://www.php.net/manual/en/language.variables.external.php

'Environment variables' is the section you want

there's a stupid function called file() that does that

Stefan, did you check your open_basedir and/or error_reporting settings in
php.ini and apache config? What are the errors?

Just because something worked before but doesn't now, doesn't mean it's a
bug in php. It's often because of default settings being different from the
settings you had before upgrade. That's not to say there can't be a bug in
php of course, but just jumping to that conclusion (apparently right away)
is silly.

You can probably help everyone by checking your side of things thouroughly
first, and then when you do report problems, provide more info.

I'm glad you've got a workaround, but it'd be nice to get to the bottom of
the problem and fix it so you can run the latest version which is what you
probably wanted when you upgraded to it. What made you reach the new
conclusion that it's a problem with the rpm, and can we work out what's
wrong with it?

I think this may fail for two reasons - it doesn't look much like valid

Javascript, basically.
Lookup the javascript event handlers, properties, and methods - 'onchange'
and 'select' would possibly be the key ones in this situation.

Re: [PHP] php vs perl

It's hard to just come out and say that php is better than perl for shopping
carts because there's too many factors to take into consideration.

If you were a person who'd never used either, I'd guess that php might be
better to use because the essential ingredients are pretty much already
included with php, such as session handling, form and url data processing,
and a wide variety of database functions.

That's not to say the same things aren't fairly easy to plug right into perl
by way of readily-available modules, but it's probably a bit of extra work,
especially for the beginner. Someone who already uses perl would likely have
libraries for these things already installed/handled anyway though.

I think the syntax might be a little easier to understand in php too,
although it's sure to be a personal preference thing to a large extent.

To me, the bottom line is go with the one you feel most
productive/comfortable with. They're both about as cross-platform portable
as each other (I think?) and both are pretty robust under heavy load,
especially when you're not using the cgi.

Re: [PHP] deleting cart items on session expire

[Jason Brooke]

You'll probably need to trigger the deletion of all expired carts with
something other than trying to guess when the user closes their browser.

Maybe a regular cronjob, or just do it inside your globally-included
function definition script so that any hit to the website can trigger it for
you, or perhaps just put it in the script that's used when creating a new
cart for someone.

Just as an aside, there's no reason I can think of that you can't run both
the Apache module and standalone binary on the same system side by side -
I've been doing this for about 2 years without trouble.

Almost, yes - I literally meant the 'common gateway interface', due to the
fact that the webserver spawns the requested script/program outside of it's
own process. I don't know the technical detals involved in doing this, but I'm
guessing that in general, it'd incur more overhead on the system than the same
code would if it was parsed by the already-running httpd process.

No there's not - I think that goes without saying though.

But while you're compiling Php anyway, why not re-run ./configure without the
'--with-apache' and add an '--enable-discard-path' and type 'make; make
install' - then you can use this awesome tool from the command line without
having to invoke a http request to your webserver usng a third-party tool.
