Quick Answer

Handle long-running PHP scripts.

Understanding the Issue

PHP has a default execution time limit (30 seconds) that prevents infinite loops and hung processes.

The Problem

This code demonstrates the issue:

Php Error 
while(true) {
    // Infinite loop
}

The Solution

Here's the corrected code:

Php Fixed 
// Solution 1: Increase time limit
set_time_limit(120); // 2 minutes

// Solution 2: Process in chunks
foreach($items as $item) {
    process_item($item);
    set_time_limit(30); // Reset counter
}

// Solution 3: CLI specific
if (PHP_SAPI === 'cli') {
    // No time limit for CLI scripts
    set_time_limit(0);
}

// Solution 4: Optimize slow code
// Profile with xdebug to find bottlenecks

Key Takeaways

Set reasonable timeouts and optimize performance-critical sections.
