PHP Code to test memory limit

<?php
// Display the current memory limit
echo "Current memory limit: " . ini_get('memory_limit') . "\n";

// Function to allocate memory
function allocateMemory($sizeInMB) {
    $sizeInBytes = $sizeInMB * 1024 * 1024;
    $memory = str_repeat('a', $sizeInBytes);
    return $memory;
}

try {
    $allocatedMemory = [];
    $i = 1;
    while (true) {
        echo "Allocating {$i}MB of memory\n";
        $allocatedMemory[] = allocateMemory(1); // Allocate 1MB at a time
        $i++;
    }
} catch (Exception $e) {
    echo "Caught exception: " . $e->getMessage() . "\n";
} catch (Error $e) {
    echo "Caught error: " . $e->getMessage() . "\n";
}
?>
