How to detect PHP execution is from cli command line?

Solution:
php_sapi_name: Returns the type of interface between web server and PHP.

Returns a lowercase string that describes the type of interface (the Server API, SAPI) that PHP is using. For example, in CLI PHP this string will be “cli” whereas with Apache it may have several different values depending on the exact SAPI used.

php_sapi_name Usage example:

php_sapi_name();
if (php_sapi_name() == 'cli') {
    echo "You are using CLI PHP";
} else {
    echo "You are not using CLI PHP";
}
