The implementation code of multidimensional array in PHP by specified value _php tips

Oh, the business needs to be sorted by a multidimensional array of elements, in PHP is also very easy to implement, a function called a callback function is done. Post the Code:

Copy Code code as follows:

$arr = Array (

' Index ' =>array (' name ' => ' home ', ' order ' =>3),

' Intro ' =>array (' name ' => ' Enterprise profile ', ' Order ' =>2),

' News ' =>array (' name ' => ' information dynamics ', ' Order ' =>1),

' Product ' =>array (' name ' => ' Products center ', ' Order ' =>4),

' Message ' =>array (' name ' => ' guestbook ', ' Order ' =>7),

' Position ' =>array (' name ' => ' talent recruitment ', ' Order ' =>6),

' Contacts ' =>array (' name ' => ' Contact us ', ' Order ' => 5)

);

Uasort ($arr, ' CMP ');

Public Function cmp ($a, $b) {

return $a ["order"]-$b [' Order '];

}

At this time $arr is ordered by order size, hehe ...
