如何根据指数中的任何一种情况,在实验室内形成一个全方位阵列?

Like i have an array say $a=array( name => sandep , dob => 06/08/1987 , education => undergrad ); i have data filled into this array based on the index. Now i want to sort the entire array data based on any one of the index. Say DOB . Is it possible to do them in PHP?

EG: if i have thousand rows. The entire array should be a sorted one based on DOB.

是的,您可使用usort使用自己的功能。

<?php 
$multiArray = Array( 
    Array("id" => 1, "name" => "Defg"), 
    Array("id" => 2, "name" => "Abcd"), 
    Array("id" => 3, "name" => "Bcde"), 
    Array("id" => 4, "name" => "Cdef")); 
$tmp = Array(); 
foreach($multiArray as &$ma) 
    $tmp[] = &$ma["name"]; 
array_multisort($tmp, $multiArray); 
foreach($multiArray as &$ma) 
    echo $ma["name"]."<br/>"; 

/* Outputs 
    Abcd 
    Bcde 
    Cdef 
    Defg 
*/ 
?>
