php - How to return control from callback function or break the processing of array in middle array

can break execution of callback once condition satisfied 1 element of array?

ex .

$a = array(1,2,3,4,5); foreach($a $val){      if ($val == 3){       break;     }  }

if write call it, below

$result = array_filter($a, function(){       if ($val == 3){           return true;         } });

in callback go through array element, in spite of condition being satisfied @ 3. rest 2 elements 4, 5 go through callback

i want such function in callback, break callback 1 desired condition match , stop execution of rest of elements

is possible?

you can a static variable. static variable of local scope inside callback function preserves value between calls.

it behaves global variable in terms of value, local scope:

$callback = function($val) {     static $filter = false;      if ($val == 3) {         $filter = true;     }      return $filter;         };

this callback return false until $val == 3. return true.
