How to get the current function name in php

How to get the current function name in php: You can get it through the magic constant __FUNCTION__. Since PHP 5, the magic constant __FUNCTION__ is used to return the name of the function when it was defined (case-sensitive).

__FUNCTION__ returns the function name (newly added in PHP 4.3.0). Since PHP 5 this constant returns the name of the function as it was defined (case sensitive). In PHP 4 this value is always lowercase.

}
test();
?>
