1Why don't you just pass a parameter when running by cron job? – Henrik Feb 16 '15 at 13:25

My hosting does not allow me to pass parameters, do not know the motivation. – Giuseppe Grieco Feb 16 '15 at 13:27

Simply use this question's answer: Using CRON jobs to visit url?
However, supply the URL with a parameter that indicates it is being from the CRON Job.
* * * * * wget -O - http://yoursite.com/script.php?fromcron=1 >/dev/null 2>&1
script.php
if(!isset($_GET['fromcron']) || $_GET['fromcron'] !== 1) {
exit();
}
// ...

If you have 2 types of requests, from server and from remote, you can determine the different between them by variable $_SERVER.
If you run a php file from php command, $_SERVER['REMOTE_ADDR'] will not be set. Therefore, you can use:
if( !isset($_SERVER['REMOTE_ADDR'] ) {
// The script is run by php command
}
However, if your 2 types of requests are run by php command, you would better use 2 php files, first is the normal one, while the second one will include the first one and also run specific script that will be run by cronjob.
