How to Increase PHP's Maximum Post Size Limits?

Enhancing Maximum Post Size Limits for Data Submission

The need arises to accommodate increased data submission due to factors beyond file uploads, resulting in the triggering of $_SERVER['CONTENT_LENGTH'] size limitations. This article explores ways to increase these limits.

There are two primary avenues for modifying the maximum post size:

php.ini Configuration File:

Within the php.ini configuration file, adjust the following directives:

• post_max_size: Sets the maximum size of POST data
• upload_max_filesize: Sets the maximum file upload size

Example PHP.ini Configuration:

post_max_size=20M
upload_max_filesize=20M

Apache Configuration File (.htaccess, httpd.conf, or Virtual Host Options):

In Apache configuration files, include the following directives:

• php_value post_max_size: Sets the maximum size of POST data
• php_value upload_max_filesize: Sets the maximum file upload size

Example Apache Configuration Directive:

php_value post_max_size 20M
php_value upload_max_filesize 20M

The choice of which method to use depends on availability and access to the relevant configuration files. Modifying the .htaccess file does not necessitate server restart, whereas changes to php.ini and other Apache configuration files require server reinitialization.
