PHP Warning: POST Content-Length of 8978294 bytes exceeds the limit…

This PHP Warning error occurs because the data being posted is larger than the maximum size allowed by the PHP configuration.

To resolve this, you need to increase the post_max_size directive in your PHP configuration file. This directive sets the maximum size of POST data that PHP will accept. By default, the value is usually set to 8MB.

To increase the post_max_size the directive, follow these steps:

Step 1: Locate your PHP configuration file

The location of your PHP configuration file depends on your operating system and the web server. Here are some common locations:

  • CentOS: /etc/php.ini
  • Ubuntu: /etc/php/7.2/apache2/php.ini
  • XAMPP: /opt/lampp/etc/php.ini
  • WAMP: C:\wamp64\bin\php\php7.4.9\php.ini

If you’re not sure where your PHP configuration file is located, you can create a new PHP file with the following code:

<?php
phpinfo();
?>

Save the file in your web server’s root directory and access it via a web browser. Look for the “Loaded Configuration File” row to find the location of your PHP configuration file.

Step 2: Edit the post_max_size directive

Once you’ve located your PHP configuration file, open it in a text editor and search for the post_max_size directive. If it’s not there, you can add it to the end of the file. The line should look like this:

post_max_size = 8M

Change the value to a higher number, like 16M. Make sure to use the appropriate unit (M for megabytes, K for kilobytes, G for gigabytes). The new line should look like this:

post_max_size = 16M

Step 3: Edit the upload_max_filesize directive

The upload_max_filesize the directive sets the maximum size of uploaded files. You should set this value to the same or a higher value than post_max_size.

Search for the upload_max_filesize the directive in your PHP configuration file and modify it as follows:

upload_max_filesize = 16M

Step 4: Save and restart your web server

Save your changes to the PHP configuration file and restart your web server to apply the new settings. The method for restarting your web server varies depending on your operating system and the web server. Here are some common methods:

  • CentOS: sudo service httpd restart
  • Ubuntu: sudo systemctl restart apache2
  • XAMPP: Click the “Stop” button and then the “Start” button in the XAMPP control panel
  • WAMP: Click the “Restart All Services” button in the WAMP control panel

After restarting your web server, the “PHP Warning: POST Content-Length of 8978294 bytes exceeds the limit of 8388608 bytes in Unknown on line 0” error message should no longer appear. You can now submit your form or upload your file without any issues.

In conclusion, to resolve the “PHP Warning: POST Content-Length of 8978294 bytes exceeds the limit of 8388608 bytes in Unknown on line 0” error message, you can increase the post_max_size and upload_max_filesize directives in your PHP configuration file and restart your web server.
