How To Fix Apache2-PHP5 File Upload and Post Max Size Issue

Ubuntu 3

In this article, we will discuss how to fix the Apache2-PHP5 file upload and post max size issue. This is a common problem that developers and system administrators encounter when working with PHP applications on Apache servers.

Before we dive into the solutions, it’s important to understand what post_max_size and upload_max_filesize are. These are directives in the php.ini file that control the maximum size of data that can be posted or uploaded using PHP. If these values are too small, you may encounter issues when trying to upload larger files.

Quick Answer

To fix the Apache2-PHP5 file upload and post max size issue, you can update the php.ini file by increasing the values of post_max_size and upload_max_filesize directives. Alternatively, you can identify and update the php.ini file used by Apache or override the settings by creating a separate .ini file. Restarting the Apache server after making the changes ensures that the updates take effect.

Solution 1: Update the php.ini file

The first solution is to directly update the php.ini file. Here’s how:

  1. Open the terminal and run the command php --ini. This command displays the loaded configuration file for the PHP CLI (Command Line Interface).
  2. Locate the php.ini file that is being used for the CLI version of PHP.
  3. Edit that php.ini file with a text editor of your choice. For instance, if you’re using nano, the command would be nano /path/to/php.ini.
  4. In the php.ini file, find and update the post_max_size and upload_max_filesize directives. For example, you might set them to 32M and 16M respectively. These values are in megabytes.
  5. Save the changes and exit the file.
  6. Restart the Apache server using the command sudo service apache2 restart. This ensures that the changes made to the php.ini file are applied.

Solution 2: Identify and Update the php.ini file used by Apache

Sometimes, the php.ini file used by the CLI is different from the one used by Apache. In that case, you need to identify the correct php.ini file and update it. Here’s how:

  1. Create a new PHP file with the following content: <?php phpinfo(); ?>. This script displays information about the PHP configuration.
  2. Save the file and open it in your web browser.
  3. Look for the “Loaded Configuration File” section. This shows the path to the php.ini file being used by Apache.
  4. Follow steps 3 to 6 from Solution 1 to update the post_max_size and upload_max_filesize directives in the identified php.ini file.

Solution 3: Override the php.ini settings

If you do not have access to the php.ini file or if your changes are not being reflected, you can create a separate .ini file to override the settings. Here’s how:

  1. Create a new PHP file with the following content: <?php phpinfo(); ?>.
  2. Save the file and open it in your web browser.
  3. Look for the “Scan this dir for additional .ini files” section. This shows the directory where additional .ini files can be placed.
  4. Go to that directory and create a new file named user.ini.
  5. In the user.ini file, add the following lines:
post_max_size = 32M
upload_max_filesize = 16M
  1. Save the changes and exit the file.
  2. Restart the Apache server using the command sudo service apache2 restart.

After applying any of these solutions, check the phpinfo output again to verify that the post_max_size and upload_max_filesize values have been updated to your desired values.

Can I override the `php.ini` settings if I don’t have access to the file?

Yes, you can create a separate .ini file to override the settings. Create a PHP file with the content <?php phpinfo(); ?> and open it in your web browser.
