Why Is My PHPMyAdmin Import File Size Still Limited to 2MB Even After Modifying php.ini?

Troubleshooting PHPMyAdmin Import File Size Limit

Despite modifying php.ini parameters like upload_max_filesize and post_max_size, users may encounter a persistent 2MB limit in PHPMyAdmin. Here's an in-depth solution that thoroughly addresses the problem.

Step-by-Step Resolution

1. Locate php.ini File: Open the terminal and use the following command to locate the php.ini file:

   sudo find / -name php.ini

2. Edit php.ini: Use a text editor like gedit to edit the file:

   sudo gedit /path/to/php.ini

3. Adjust Config Settings: Search for the following entries and make the necessary adjustments:

   • post_max_size: Set this to a value larger than the size of your database (e.g., 25M).
   • memory_limit: Set this to a value larger than post_max_size (e.g., 30M).
   • upload_max_filesize: Set this to a value smaller than post_max_size (e.g., 20M).

The order of settings should be:

memory_limit > post_max_size > upload_max_filesize

4. Save and Restart Apache: After saving the changes, restart Apache to apply the new settings:

   sudo systemctl restart apache2

Additional Tips

• Ensure the target database has sufficient storage space to accommodate the imported file.
• Clear browser cache and try again.
• If using a Windows machine, check the XAMPP control panel for additional size limits.
