call_user_func_array()

mixed call_user_func_array ( callable $callback , array $param_arr )

调用回调函数，并把一个数组参数作为回调函数的参数

<?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
