PHP Accessing static properies via variable

Question

Is there any way to access static property via variable that holds property name(Except of ReflectionClass and eval())?

class WhateverClass
{
    public static $test = array('1','2');
    public static $other = array('3','4');
}
$propName = 'test';
var_dump(WhateverClass::$propName);

I think you need to use double $ syntax for this. Look up variable variables in PHP's manual. — GordonM

I tried something like ` WhateverClass::{$propName}`. I totally forgot about $$. Thanks all. — Sergey Shcherbin

The following should work:

var_dump(WhateverClass::$$propName);

This is known as variable variables

I'd try to minimise my use of that technique though, it could get very confusing very quickly if overused.

You need to use "variable variables".

$propName = 'test';
var_dump(WhateverClass::$$propName);

Note the two $. That tells PHP to look for variable named... whatever $propName contains.
