php array_map with static method of object

Question

I want to use array_map with a static method but I fail. Here is my code :

Class Buy {      public function payAllBills() {         $bill_list = OtherClass::getBillList();         return array_map(array(self, 'pay'), $bill_list); // Issue line     }      private static function pay($bill) {         // Some stuff         return true;     }  } 

PHP gives me the error :

Use of undefined constant self - assumed 'self' 

I have also tried :

return array_map('self::makeBean()', $model_list); 

But it doesn't work.

Do you have any idea how to use array_map with static method ?

I have already read : Can a method be used as a array_map function in PHP 5.2? but this question is about standard methods, not statics.

Answer 1

As per the documentation,

return array_map('self::pay', $model_list); 

Note that your attempt included () in the method name string, which would be wrong
