This article tells the difference between magic variables __METHOD__ and __FUNCTION__ in PHP, and shares it for your reference. The specific analysis is as follows:
The method name of the __METHOD__ class (newly added to PHP 5.0. 0). Returns the name (case-sensitive) of the method when it was defined.
__FUNCTION__ function name (PHP 4.3. 0 newly added). Since PHP 5, this constant returns the name (case-sensitive) of the function when it was defined. This value is always lowercase in PHP 4.
Documentation is all about returning the name of the function (method). The difference is:
__FUNCTION__ just returns the name of the method;
__METHOD__ Returns the name of the class and the name of the method.
<?php
class Test{
public function doit(){
echo __FUNCTION__;
}
public function doitAgain(){
echo __METHOD__;
}
}
$obj = new Test();
$obj->doit();
echo '<br>';
$obj->doitAgain();
?>
The output is:
doit
Test::doitAgain
