Setting up a PHP Info File
Before you even start trying out different solutions, it can be useful to try and get some details about how PHP is configured on your site. Luckily, PHP has a simple function to help you do this. Create a new file in a text editor of your choice, and add this line of code to it:
<?php phpinfo(); ?>
Name the file “info.php” and save it. Then, FTP into the root directory of your server, where WordPress is installed, and drag in info.php. Next, visit “
http://yoursite.com/info.php”, replacing “yoursite.com” with the actual URL of your live site. This will give you a full list of details about your PHP configuration.
There’s a lot here, but you can ignore most of it. The most important part of this file is which PHP version you are running. This will be shown in block letters at the top, for instance “PHP Version 5.4.16”. It’s most important to pay attention to the first number of your version. You will either be running a version of PHP 4 or PHP 5. Some of the tips outlined here will require you to know which version you are running, so take note of it.
There are three settings within the PHP info file that are relevant to your upload limit. You can search through the file to see what they are currently set to.
- memory_limit – This defines how much memory is allocated to PHP. You will simply need to ensure that this number is as high or higher than the upload limit you want to set.
- post_max_size – This defines the maximum size that is handled in a POST request. We will need to set this to our new upload limit.
- upload_max_filesize – This defines the maximum size for file uploads. This will also be set to our new upload limit.
Now that we have a little bit of info about our PHP set-up, we can try a few different methods for increasing our file size limit.
