In most cases you can distinguish if a PHP script was invoked from the command line (or Cron) or by the web server, using php_sapi_name().
php_sapi_name() will return cli on CLI (or Cron) invocation and some other values on invocation by Web Server (e.g. apache2handler for Apache).
Example
A simple example:
<?php
if(php_sapi_name() == 'cli') {
// your code here
} else {
// your code here
}
?>
