A

 

why is that?

 

i have this code

 

<?php

 

var_dump($_POST);

 

?>

 

i make a GET request to that page , it will show : array(0) { }

 

if it was not initialized it would have been NULL ,

C is indeed the correct answer.

 

__FILE__ The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2, __FILE__ always contains an absolute path with symlinks resolved whereas in older versions it contained relative path under some circumstances.

 

of couse it is also a magic constant , but why is my answer not right?
