Are there any specific best practices for optimizing PHP scripts that run continuously?

When optimizing PHP scripts that run continuously, it is important to minimize memory usage and optimize performance to prevent memory leaks and ensure efficient processing. One way to achieve this is by regularly checking for memory usage and implementing proper memory management techniques such as freeing up memory when it is no longer needed. 

// Check memory usage and free up memory if necessary
$memoryLimit = 128; // Set memory limit in MB
$memoryUsage = memory_get_usage(true) / 1024 / 1024; // Get current memory usage in MB

if ($memoryUsage > $memoryLimit) {
    // Free up memory by unsetting variables or objects
    // Example: unset($variable);
}
