    Hello Reader's! if you have an given array on with you want to sort with any selected key index as show below:-

    1. Array

    4.                 (
    5.                     [configuration_id] => 10
    6.                     [id] => 1
    7.                     [optionNumber] => 3
    8.                     [optionActive] => 1
    9.                     [lastUpdated] => 2010-03-17 15:44:12
    10.                 )
    11.  
    12.             [1] => Array
    13.                 (
    14.                     [configuration_id] => 9
    15.                     [id] => 1
    16.                     [optionNumber] => 2
    17.                     [optionActive] => 1
    18.                     [lastUpdated] => 2010-03-17 15:44:12
    19.                 )
    20.  
    21.             [2] => Array
    22.                 (
    23.                     [configuration_id] => 8
    24.                     [id] => 1
    25.                     [optionNumber] => 1
    26.                     [optionActive] => 1
    27.                     [lastUpdated] => 2010-03-17 15:44:12
    28.                 )
    29.     )

    And you want your array to be like this:-

    1.  Array
    2.             (
    3.                 [0] => Array
    4.                     (
    5.                         [configuration_id] => 8
    6.                         [id] => 1
    7.                         [optionNumber] => 1
    8.                         [optionActive] => 1
    9.                         [lastUpdated] => 2010-03-17 15:44:12
    10.                     )
    11.  
    12.                 [1] => Array
    13.                     (
    14.                         [configuration_id] => 9
    15.                         [id] => 1
    16.                         [optionNumber] => 2
    17.                         [optionActive] => 1
    18.                         [lastUpdated] => 2010-03-17 15:44:12
    19.                     )
    20.  
    21.                 [2] => Array
    22.                     (
    23.                         [configuration_id] => 10
    24.                         [id] => 1
    25.                         [optionNumber] => 3
    26.                         [optionActive] => 1
    27.                         [lastUpdated] => 2010-03-17 15:44:12
    28.                     )
    29.         )

    Now you have to use the code as written below:- 

    1. function cmp_by_optionNumber($a, $b) {
    2.   return $a["optionNumber"] - $b["optionNumber"];
    3. }
    4.  
    5. usort($array, "cmp_by_optionNumber");
    php
