I would create a simple text file to log every time your script executes.
Could be as simple as
Code:
$logfile = fopen('mylogfile.txt','a');
fwrite($logfile, 'My script was executed at' . date('Y-m-d H:i:s');
fclose($logfile);
This will give you a record of all launches, as well as updating the file's timestamp
so you can see if it was changed even just by looking at the 'last changed' date.
