问如何在php中为人类(自然排序)排序关联数组？

EN

<?php

function record_sort($records, $field, $reverse=false)
 {
     $hash = array();

    foreach($records as $record)
     {
         $hash[$record[$field]] = $record;
     }

    ($reverse)? krsort($hash) : ksort($hash);

    $records = array();

    foreach($hash as $record)
     {
         $records []= $record;
     }

    return $records;
 }

// Example below

$airports = array
 (
     array( "code" => "LHR", "name" => "Heathrow" ),
     array( "code" => "LGW", "name" => "Gatwick" ),
 );

printf("Before: <pre>%s</pre>", print_r($airports, true));

$airports = record_sort($airports, "name");

printf("After: <pre>%s</pre>", print_r($airports, true));

?>

Example Outputs:

Before: Array
 (
     [0] => Array ( [code] => LHR, [name] => Heathrow )
     [1] => Array ( [code] => LGW, [name] => Gatwick )
 )

After: Array
 (
     [0] => Array ( [code] => LGW, [name] => Gatwick )
     [1] => Array ( [code] => LHR, [name] => Heathrow )
 )
