对多维数组按某值排序的php代码，供大家参考。

复制代码代码如下:

<?php

    $arr = array(

                 "0" => array(line_num => "10", occur_time => "2007-11-19 10:25:04+08"),

             　　 "1" => array(line_num => "9", occur_time => "2007-11-19 10:25:04+08"),

                　"2" => array(line_num => "25", occur_time => "2007-11-19 10:25:04+08")

                );

    print_r($arr);

    echo "<br />";

    echo "<br />";

    echo "<br />";

    uasort( $arr,create_function('$a, $b', 'return $a['line_num'] < $b['line_num'];') );

    print_r($arr);

    echo "<br />";

    echo "<br />";

    echo "<br />";

    foreach($arr as $key => $value) {

        $ar[] = $value;

    }

    print_r($ar);

?>

输出结果：
Array
(
 [0] => Array
 (
 [line_num] => 10
 [occur_time] => 2007-11-19 10:25:04+08
 )
 [1] => Array
 (
 [line_num] => 9
 [occur_time] => 2007-11-19 10:25:04+08
 )
 [2] => Array
 (
 [line_num] => 25
 [occur_time] => 2007-11-19 10:25:04+08
 )
)

 [2] => Array

 (
 [line_num] => 10
 [occur_time] => 2007-11-19 10:25:04+08
