Quick Answer

Handle large form submissions.

Understanding the Issue

This warning occurs when POST data exceeds server limits.

The Problem

This code demonstrates the issue:

Php Error 
// Large file upload fails

The Solution

Here's the corrected code:

Php Fixed 
// Increase limits in php.ini:
; post_max_size = 20M
; upload_max_filesize = 20M

// Check upload status
if ($_SERVER['CONTENT_LENGTH'] > 0 && empty($_POST)) {
    die("POST data exceeded limits");
}

// Chunked uploads
$chunk = file_get_contents("php://input");

// Alternative: increase limits temporarily
ini_set("post_max_size", "20M");
ini_set("upload_max_filesize", "20M");

Key Takeaways

Adjust server limits and implement chunking for large uploads.
