PHP Difference of two assoc Arrays -

i have 2 arrays of assoc arrays:

first one:

array (     [0] => array         (             [24] => s             [23] => czarny         )      [1] => array         (             [24] => m             [23] => czarny         )      [2] => array         (             [24] => l             [23] => czarny         )  ) 

and second:

array (     [0] => array         (             [24] => l             [23] => czarny         )      [1] => array         (             [23] => czarny             [24] => m         )  ) 

in output get:

array (       [24] => s       [23] => czarny ) 

because 2 of arrays:

[0] => array         (             [23] => czarny             [24] => m         ) 

and

[0] => array         (             [24] => m             [23] => czarny         ) 

are same me. have idea how deal that? tried fourth nested foreach got confused..

this little loop crazy, work.

$array1[0][23] = 'czarny'; $array1[0][24] = 'm';  $array1[1][23] = 'czarny'; $array1[1][24] = 's';  $array1[2][23] = 'czarny'; $array1[2][24] = 'l';  $array2[0][23] = 'czarny'; $array2[0][24] = 'm';  $array2[1][23] = 'czarny'; $array2[1][24] = 'l';  end($array1);  // merge 2 arrays $array3 =   array_merge($array1,$array2); // loop through 1 array , create second assoc array based on key 24 foreach($array1 $mainkey => $object) {         foreach($object $key => $value) {                 $newarray[$object[24]][$key] = $value;             }     } // loop through new array create yet new 1 reset keys numeric $i=0; foreach($newarray $key => $value) {         $final[$i]  =   $value;          $i++;     }  print_r($final);
