In the context of game server management, what are some alternative approaches to continuously running PHP scripts, such as using file checks or external triggers, to improve script control and resource management?

When continuously running PHP scripts on a game server, it's important to consider alternative approaches to improve script control and resource management. One way to achieve this is by using file checks or external triggers to determine when the script should run or stop, rather than running the script indefinitely. This can help prevent resource exhaustion and ensure that the script only runs when necessary.

// Example of using file checks to control PHP script execution
$runFile = '/path/to/run.txt';

while (file_exists($runFile)) {
    // Your script logic here
    // This will continue running as long as the run file exists
    // Make sure to delete the run file when you want the script to stop
}
