Question

i am building a class and it contains some methods

in some method i tried to use [array_map][1] function and make it’s $callback a method which is defined inside the same class so i tried

array_map('$this->something()',$this->somearray);

but it didn’t work ! and caused this error

function '$this->something' not found or invalid

any ideas to use an internal method in the class as a callback ?

If you’re using PHP >= 5.3 then just use a closure.

array_map(function($a) {}, $this->somearray);

Otherwise it should be:

array_map(array($this, 'something'), $this->somearray);
