Array_map function in php with parameter

Question

I have this

$ids = array_map(array($this, 'myarraymap'), $data['student_teacher']);  function myarraymap($item) {     return $item['user_id']; } 

I will would like to put an other parameter to my function to get something like

function myarraymap($item,$item2) {     return $item['$item2']; } 

Can someone can help me ? I tried lots of things but nothing work

Answer 1

You can use an anonymous function and transmit value of local variable into your myarraymap second argument this way:

function myarraymap($item,$item2) {     return $item[$item2]; }  $param = 'some_value';  $ids = array_map(     function($item) use ($param) { return myarraymap($item, $param); },     $data['student_teacher'] ); 

Normally it may be enough to just pass value inside anonymous function body:

function($item) { return myarraymap($item, 'some_value'); }
