动态调用静态函数？

Question

Could someone fill in the blank. I need to call a static function on a class. Do I need to use eval here?

// Some settings require function calls
$switch = array ('random_image' => 'Splashpage::get_random_image()', 'splash_photos_count' => 'Splashpage::count_splash_photos()');
foreach($switch as $key => $function) {
    if ($name == $key) {
        return ... $function
    }
}

Everyone has been partly right.

Firstly this array is wrong.

$switch = array ('random_image' => 'Splashpage::get_random_image()', 'splash_photos_count' => 'Splashpage::count_splash_photos()');

It should be:

$switch = array ('random_image' => 'Splashpage::get_random_image', 'splash_photos_count' => 'Splashpage::count_splash_photos');

This allows you to call - as 2 people have said - call_user_func and bobs your uncle.

$switch = array ('random_image' => 'Splashpage::get_random_image', 'splash_photos_count' => 'Splashpage::count_splash_photos');
if(isset($switch[$name])) {
    return call_user_func($switch[$name]);
}
