<?php

function foobar($arg, $arg2) {

    echo __FUNCTION__, " got $arg and $arg2\n";

}

class foo {

    function bar($arg, $arg2) {

        echo __METHOD__, " got $arg and $arg2\n";

    }

}

// Call the foobar() function with 2 arguments

call_user_func_array("foobar", array("one", "two"));

// Call the $foo->bar() method with 2 arguments

$foo = new foo;

call_user_func_array(array($foo, "bar"), array("three", "four"));

?>  

以上例程的输出类似于：

foobar got one and two

foo::bar got three and four
