How can I check if two array are same

This is my array

[51] => Array
    (
        [171] => 34
        [170] => Adult
        [168] => 32
        [quantity] => 1
    )

[52] => Array
    (
        [171] => 34
        [170] => Adult
        [168] => 32
        [quantity] => 1
    )

Now if all the keys and value except quantity are same then the quantity will be added.

ex:

 [51] => Array
    (
        [171] => 34
        [170] => Adult
        [168] => 32
        [quantity] => 2
    )

Is there any way to search with dynamic keys. Please help.

Suppose that

$arr1 = Array(
    171 => 34
    170 => Adult
    168 => 32
    'quantity' => 1
);

$arr2 = Array(
    171 => 34
    170 => Adult
    168 => 32
    'quantity' => 1
);

you could do the following:

$tmp1 = $arr1;
unset($tmp1['quantity']);

$tmp2 = $arr2;
unset($tmp2['quantity']);

if($tmp1 == $tmp2) {
  // do what you like
}

when you do $tmp1 == $tmp2 it compares the two arrays by key and value, see http://php.net/manual/en/language.operators.array.php

$a == $b TRUE if $a and $b have the same key/value pairs.

$a === $b TRUE if $a and $b have the same key/value pairs in the same order and of the same types.

You can use array_diff_assoc() function ... it checks array based on key

   <?php
      $array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
      $array2 = array("a" => "green", "yellow", "red");
      $result = array_diff_assoc($array1, $array2);
      print_r($result);
    ?>
