PHP : anonymous function in associative array

Question

有可能吗？类似的东西(不起作用):

$prototype = array(
    'ext' => function ($args)
    {
        $ext = NULL;
        if (in_array(func_get_arg(0), array('js', 'css')))
            return $ext;
        else
            return 'js';
    },
);

Answer 1

是的。唯一的限制是您无法将其转换为对象。

<?php
    $foo = array(
        'bar' => function($text)
        {
            echo $text;
        }
    );
    $foo['bar']('test'); //prints "test"

    $obj = (object)$foo;
    $obj->bar('test'); //Fatal error: Call to undefined method stdClass::bar() in /code/REGnPf on line 11
?>
