This article mainly introduces the difference between the magic variable _ METHOD _ and _ FUNCTION _ in PHP. it is a concept that must be mastered in PHP programming and is of great practical value, for more information about the differences between the magic variables _ METHOD _ and _ FUNCTION _ in PHP, see the examples in this article. The specific analysis is as follows:
_ METHOD _ class METHOD name (new PHP 5.0.0 ). Returns the name (case sensitive) when the method is defined ).
_ FUNCTION name (new in PHP 4.3.0 ). Starting from PHP 5, this constant returns the name (case sensitive) when the function is defined ). In PHP 4, the value is always lowercase letters.
The document explains the name of the returned function (method. The difference is:
_ FUNCTION _ only returns the name of the method;
_ METHOD _ return the class name and METHOD name.
<? Php class Test {public function doit () {echo _ FUNCTION __;} public function doitAgain () {echo _ METHOD __;}}$ obj = new Test (); $ obj-> doit (); echo'
'; $ Obj-> doitAgain ();?>
Output result:
DoitTest: doitAgain
