Quick Answer

Handle PHP memory limits.

Understanding the Issue

This error occurs when a script exceeds PHP"s memory allocation, often from processing large datasets or memory leaks.

The Problem

This code demonstrates the issue:

Php Error 
<?php
$data = [];
while (true) {
    $data[] = str_repeat("x", 1024*1024); // 1MB chunks
}

The Solution

Here's the corrected code:

Php Fixed 
<?php
// Increase memory limit
ini_set("memory_limit", "256M");

// Process in chunks
$file = fopen("large.csv", "r");
while ($row = fgetcsv($file)) {
    processRow($row);
}
fclose($file);

// Free memory
unset($largeArray);
gc_collect_cycles();

Key Takeaways

Optimize memory usage or increase limits for large operations.
