I'm using PHP 5.3.0 and have encountered something that might be a bug (in which case I'll report it) or might be me - so I'm asking to make sure.

When running this code:

ini_set('upload_max_filesize', '10M');
echo ini_get('upload_max_filesize'), ", " , ini_get('post_max_size')

I end up with:

2M, 8M

This is despite my php.ini setting these higher:

upload_max_filesize = 10M
post_max_size = 10M

(occuring only once)

Because the error occurs after setting the value as well as it being set in php.ini I'm inclined to think it's a bug. Can anyone confirm or point me where I'm going wrong?

Update: Looks like restarting Apache fixed this - I always thought it didn't need to be restarted if you changed php.ini.

Solution 1

You can't use shorthand notation to set configuration values outside of PHP.ini. I assume it's falling back to 2MB as the compiled default when confronted with a bad value.

On the other hand, I don't think upload_max_filesize could be set using ini_set(). The "official" list states that it is PHP_INI_PERDIR .

Solution 2

Are you using a shared hosting provider? It could be master settings overriding anything you're trying to change. Have you tried adding those into your .htaccess?

php_value upload_max_filesize 10M
php_value post_max_size 10M

Solution 3

Since I just ran in to this problem on a shared host and was unable to add the values to my .htaccess file I thought I'd share my solution.

I made an ini file with the values in it. Simple as that:

Make a file called ".user.ini" and add your values

upload_max_filesize = 150M
post_max_size = 150M

Boom, problem solved.

Solution 4

I got this to work using a .user.ini file in the same directory as my index.php script that loads my app. Here are the contents:

upload_max_filesize = "20M"
post_max_size = "25M"

This is the recommended solution for Heroku.

Solution 5

This can also be controlled with the apache configuration. Check the httpd.conf and/or .htaccess for something like the following:

php_value upload_max_filesize 10M

Solution 6

If you are running in a local server, such as wamp or xampp, make sure it's using the php.ini you think it is. These servers usually default to a php.ini that's not in your html docs folder.

Solution 7

I've faced the same problem , but I found out that not all the configuration settings could be set using ini_set() function , check this Where a configuration setting may be set

Solution 8

if you use ini_set on the fly then you will find here http://php.net/manual/en/ini.core.php the information that e.g. upload_max_filesize and post_max_size is not changeable on the fly (PHP_INI_PERDIR).

Only a php.ini, .htaccess or vhost config change seems to change these variables.

This solution can be applied only if the issue is on a WordPress installation!

If you don't have FTP access or too lazy to edit files,

You can use Increase Maximum Upload File Size plugin to increase the maximum upload file size.

Solution 10

You can use also in the php file like this

<?php ini_set('upload_max_filesize', '200M'); ?>
