[SOLVED] Help needed with ereg_replace

[mattyf]

Hello

 

I've inherited a site that was running on IIS and I have no previous experience with ereg_replace. The code below (companies.php) works on the IIS server but returns a 404 on my Linux VPS.

 

From what I can ascertain, the second line of code should return companies.login from the following address:

 

http://www.domain.com/folder/companies.php/login.html

 

<?php
$_SERVER['PATH_INFO']=ereg_replace('/$','/index.html',$_SERVER['PATH_INFO']);

$_GET['mods']=ereg_replace('\.php$','',substr($_SERVER['PHP_SELF'],15)).ereg_replace('\.(php|html)$','',$_SERVER['PATH_INFO']);

$_GET['ext']=ereg_replace('.*\.','',$_SERVER['PATH_INFO']);

require('index.php');
?>

 

If I hard code

$_GET['mods'] ="companies.login";

it works for that one page, but then obviously not for others.

 

I'd greatly appreciate any pointers.

 

Thanks!

I'm not a POSIX regex expert, but I think this is what that means:

 

<?php

// Replace a trailing slash in $_SERVER['PATH_INFO'] with /index.html
$_SERVER['PATH_INFO']=ereg_replace('/$','/index.html',$_SERVER['PATH_INFO']);

/* Set $_GET['mods'] equal to the first 15 characters of $_SERVER['PHP_SELF'],
minus a possible ".php" on the end, plus $_SERVER['PATH_INFO'] less a trailing
".php" or ".html" */
$_GET['mods']=ereg_replace('\.php$','',substr($_SERVER['PHP_SELF'],15))
. ereg_replace('\.(php|html)$','',$_SERVER['PATH_INFO']);

// Set $_GET['ext'] equal to anything after the last period (i.e., the ".php" or ".html") in $_SERVER['PATH_INFO']
$_GET['ext']=ereg_replace('.*\.','',$_SERVER['PATH_INFO']);
?>

Thank you for taking the time to reply, that's really useful.

 

It looks like it may be an issue with the use of

$_SERVER['PATH_INFO']

 

I made a page

<?php
print 'PATH_INFO: '. $_SERVER['PATH_INFO']. "<br>\n";
print 'ORIG_PATH_INFO: '. $_SERVER['ORIG_PATH_INFO']. "<br>\n";
?>

and set acceptpathinfo=On

 

but I just get:

 

PATH_INFO:

ORIG_PATH_INFO:

 

Apache version is 4.3.9 - maybe path_info isn't supported?

[Wildbug]

It might be.  I didn't get PATH_INFO either (I did get ORIG_PATH_INFO on phpinfo()), but I figured it might be a configuration or version issue on my end.  If you don't have it either, that's probably your problem, and you'll need to find a better variable with the same/comparable value to extract the data from.  Do you know what data the original script needed from those vars?

 

You mean PHP version 4.3.9?

[mattyf]

Sorry, yes I meant to say PHP version 4.3.9.

 

PHP_SELF could provide a solution with a little more assistance 

 

<?php
$_SERVER['PATH_INFO']=ereg_replace('/$','/index.html',$_SERVER['PHP_SELF']);

$_GET['mods']=ereg_replace('\.php$','',substr($_SERVER['PHP_SELF'],0)).ereg_replace('\.(php|html)$','',$_SERVER['PHP_SELF']);

print 'PATH_INFO: '. $_SERVER['PATH_INFO']. "<br>\n";
print 'mods: '. $_GET['mods']. "<br>\n";
?>

 

Outputs:

 

PATH_INFO: /directory/companies.php/login.html

mods: /directory/companies.php/login.html/directory/companies.php/login

 

But in this example I need mods to = companies.login

 

I've tried a number of combinations, and can achieve companies/login but can't quite work out how to replace the / with a .

[mattyf]

Fixed it!

<?php
$_GET['mods']=preg_replace('#^/directory/([a-z]*)\.php/(.*)\.(php|html)$#', '\\1.\\2',$_SERVER['PATH_INFO']);
?>

 

Thanks for your guidance Wildbug!
