Method 1: | |
--------- | |
If you are executing PHP directly from the Cron Job e.g. php /path/to/your_script.php then add the following line at the top of your PHP script: | |
if (php_sapi_name() !='cli') exit; | |
Method 2: | |
--------- | |
if the Cron Job uses wget, curl or lynx to run your script via its URL, then insert this code at the top of your PHP script (change the User Agent string to one known only by you) : | |
if ($_SERVER['HTTP_USER_AGENT'] != 'yourSecretAgent') exit; | |
You will also have to set the User Agent in the Cron Job; as in this wget example: | |
wget -O - --user-agent=“yourSecretAgent” http://example.com/your_script.php |
