Quick Answer

Handle long-running scripts.

Understanding the Issue

PHP scripts have a default 30-second execution limit, which can be exceeded by complex operations or infinite loops.

The Problem

This code demonstrates the issue:

Php Error 
<?php
while (true) {
    // Infinite loop
}

The Solution

Here's the corrected code:

Php Fixed 
<?php
// Increase time limit
set_time_limit(300); // 5 minutes

// Break into chunks
foreach ($items as $item) {
    process($item);
    set_time_limit(30); // Reset counter
}

// Asynchronous alternative
exec("php long_process.php > /dev/null &");

Key Takeaways

Adjust time limits or optimize lengthy operations.
