file uploading problem with mediaWiki
I am using MediaWiki (the Wikipedia wiki) for some internal work.
Today one of our users had some trouble uploading a large PDF file.
I checked the wiki code and I could find any file size restriction.
It turns out that the problem does not come from MediaWiki but from the underlying PHP engine.
After googling for a bit, I discovered the existence of a magic file called php.ini with some magic variables such as memory_limit, post_max_size, upload_max_filesize.
See here for instance.
Creating the php.ini file is easy. Making Apache and PHP find it is not.
After a couple of unsuccessful attempts, here is the best way to do it:
- create a php.ini file under /etc
- create a info.php file in the root of your mediawiki, next to index.php
- restart Apache (yes, you have to)
- go to info.php and it will tell you where Apache/PHP is looking for the php.ini file
- create a symbolic link from /etc/php.ini to this folder
- restart Apache (you know the drill now)
PS: if you are like me and never remember where and how Apache was started on your machine, try this:
ps -A -o uid,comm,args | grep httpd
PPS: here is the code for info.php.
<html>
<head>
<title>PHP Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<body>
<h1>PHP Information</h1>

< ?php phpinfo(); ?>
