Variable as static function

Question

I have a class Sections:

class Sections {
    public static function get($name) {
        //
    }
}

And I would like to call the static function get() from it with a variable (http://php.net/manual/en/functions.variable-functions.php):

$section = 'Sections::get';
$section('body');

But it gives me a Fatal error: Call to undefined function Sections::get()

Is it possible to call a static function in this way?

Thanks!

You need to store the class separately from the method:

$class = 'Sections';
$method = 'get';

Now you can call it like this:

$class::$method('body');

Try using call_user_func to do this:

$section = array('Sections', 'get');
call_user_func($section, 'body');

Or:

$section = 'Sections::get';
call_user_func($section, 'body');

A problem that I see with your solution is that in stacktraces you'll only see call_user_func() but not Sections::get() which makes the trace less worth for debugging. That's why I try to avoid call_user_func() whenever possible.

I've solved it with the help of a function outside of the class:

class Sections {
    public static function get($name) {
        //
    }
}

function section($name) {
    Sections::get($name);
}

Now I can do:

$section = 'section';
$section('body');
