對多維陣列按某值排序的php代碼

$arr = array( "0" => array(line_num => "10", occur_time => "2007-11-19 10:25:04+08"), 　　 "1" => array(line_num => "9", occur_time => "2007-11-19 10:25:04+08"), 　"2" => array(line_num => "25", occur_time => "2007-11-19 10:25:04+08") ); print_r($arr); echo " "; echo " "; echo " "; uasort( $arr,create_function('$a, $b', 'return $a[\'line_num\'] < $b[\'line_num\'];') ); print_r($arr); echo " "; echo " "; echo " "; foreach($arr as $key => $value) { $ar[] = $value; } print_r($ar); ?> 複製代碼 輸出結果：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 )) Array( [2] => Array ( [line_num] => 25 [occur_time] => 2007-11-19 10:25:04+08 ) [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 )) Array( [0] => Array ( [line_num] => 25 [occur_time] => 2007-11-19 10:25:04+08 ) [1] => Array ( [line_num] => 10 [occur_time] => 2007-11-19 10:25:04+08 ) [2] => Array ( [line_num] => 9 [occur_time] => 2007-11-19 10:25:04+08 )) >>> 更多內容，請查看 php數組排序方法大全 <<<
