Jhon,
You can use this code below to automatically check a file to see if it has been locked and if it has not the script when ran will lock onto the specified file.
If the file cannot be locked onto the script also allows you to receive an error message telling you that the file is locked by another process and terminate.
<?php
    $fp = fopen("fileyouaretryingtolock.txt", "w");
    if (flock($fp, LOCK_EX | LOCK_NB)) {
        echo "Lock is achieved!n";
        sleep(10);
        flock($fp, LOCK_UN);
    } else {
        print "File is locked by another process!n";
    }
?>
