PHP equivalent of Python's __name__ == “__main__”?

Question

As per the title, is there PHP equivalent of __name__ == \"__main__\"?

Is there something that would work for both scripts executed through the command line

Answer 1

if ($argv && $argv[0] && realpath($argv[0]) === __FILE__) {
    // ...
}

works like a charm.

when you run php in command line, the name of php file will pass to program as $argv[0] and __FILE__ magic variable mean current file. So we check the running program is current file logically equals Python's __name__ == "__main__".
