How can PHP be used to monitor the status of a script running ffmpeg encoding in the background?

To monitor the status of a script running ffmpeg encoding in the background using PHP, you can create a separate PHP script that checks the status of the ffmpeg process by using the `exec()` function to run system commands. You can check if the process is still running, retrieve its PID, or monitor the output log file for progress updates. 

<?php
// Check if the ffmpeg process is running
exec("pgrep ffmpeg", $pids);

if (!empty($pids)) {
    echo "FFmpeg process is running with PID: " . $pids[0];
} else {
    echo "FFmpeg process is not running";
}

// Alternatively, you can monitor the output log file for progress updates
$logFile = '/path/to/ffmpeg.log';
if (file_exists($logFile)) {
    $logContent = file_get_contents($logFile);
    echo "FFmpeg log file content: " . $logContent;
} else {
    echo "FFmpeg log file not found";
}
?>
