Setting the PHP maximum upload file size in an .htaccess file

The upload_max_filesize directive in PHP defines the largest file size that can be uploaded through scripts. By default, this value is often set to 2 MB or 8 MB depending on the hosting environment. On ruachost.com, you can override this limit using a custom .htaccess file.

???? Why Change upload_max_filesize?

• Allow larger uploads (images, videos, PDFs, backups).

• Support CMS platforms like WordPress or Joomla that require bigger limits.

• Prevent errors such as:

  The uploaded file exceeds the upload_max_filesize directive in php.ini.

Steps to Set upload_max_filesize in .htaccess

Step 1: Access Your Hosting Account

• Log in to cPanel or use FTP/File Manager.
• Navigate to your site’s root directory (e.g., /public_html).

Step 2: Create or Edit .htaccess

1. If .htaccess already exists, open it for editing.
2. If not, create a new file named .htaccess.

Step 3: Add the Directives

Insert the following lines:

php_value upload_max_filesize 64M
php_value post_max_size 64M

• Replace 64M with the desired size (e.g., 128M).
• Always set post_max_size equal to or larger than upload_max_filesize.

Step 4: Save and Verify

1. Save the .htaccess file.

2. Create a test file info.php with:

   <?php phpinfo(); ?>

3. Load it in your browser and search for upload_max_filesize and post_max_size.

4. Confirm the new values are active.

5. Delete the test file afterward for security.

Important Notes

• Not all hosting environments allow PHP directives in .htaccess. If unsupported, use php.ini or .user.ini.
• Incorrect syntax in .htaccess can cause 500 Internal Server Errors.
• Always back up your .htaccess file before making changes.

Best Practices

• Increase gradually (e.g., 32M → 64M → 128M).
• Adjust related directives (memory_limit, max_execution_time) for very large uploads.
• Test uploads after making changes to ensure stability.
