How do I handle large form submissions with $_POST?

Handling large form submissions with $_POST involves considerations for both server and client-side limitations:

• Increase Post Size Limit: Adjust the post_max_size and upload_max_filesize directives in the PHP configuration file (php.ini) to allow larger data submissions.
• Optimize Data Handling: Process the data in chunks if it is too large to handle in one go. Use pagination or incremental data processing techniques.
• Validate Data Size: Check the size of the data before processing it. Ensure it does not exceed expected limits and handle errors gracefully.
