【收藏】php实现二维数组排序

php关于数组操作的函数很多，然而没有一个函数能够对二维数组排序，然而在实现的项目开发过程中有时候我们需要对二维数组排序，那么下面的这段代码就能满足需求了，能很好地对二维数组排序：

<?php/** * Sort an two-dimension array by some level two items use array_multisort() function. * * sysSortArray($Array,"Key1","SORT_ASC","SORT_RETULAR","Key2"……) * @author                      Chunsheng Wang <[e-mail]> * @param  array   $ArrayData   the array to sort. * @param  string  $KeyName1    the first item to sort by. * @param  string  $SortOrder1  the order to sort by("SORT_ASC"|"SORT_DESC") * @param  string  $SortType1   the sort type("SORT_REGULAR"|"SORT_NUMERIC"|"SORT_STRING") * @return array                sorted array. */function sysSortArray($ArrayData, $KeyName1, $SortOrder1 = "SORT_ASC", $SortType1 = "SORT_REGULAR") {    if (!is_array($ArrayData)) {        return $ArrayData;    }    // Get args number.    $ArgCount = func_num_args();    // Get keys to sort by and put them to SortRule array.    for ($I = 1; $I < $ArgCount; $I++) {        $Arg = func_get_arg($I);        if (!eregi("SORT", $Arg)) {            $KeyNameList[] = $Arg;            $SortRule[] = '$' . $Arg;        } else {            $SortRule[] = $Arg;        }    }    // Get the values according to the keys and put them to array.    foreach ($ArrayData AS $Key => $Info) {        foreach ($KeyNameList AS $KeyName) {            ${$KeyName}[$Key] = $Info[$KeyName];        }    }    // Create the eval string and eval it.    $EvalString = 'array_multisort(' . join(",", $SortRule) . ',$ArrayData);';    eval($EvalString);    return $ArrayData;}//################# 示例 #################$arr = array(    array(        'name' => '学习',        'size' => '1235',        'type' => 'jpe',        'time' => '1921-11-13',        'class' => 'dd',    ),    array(        'name' => '中国功夫',        'size' => '153',        'type' => 'jpe',        'time' => '2005-11-13',        'class' => 'jj',    ),    array(        'name' => '编程',        'size' => '35',        'type' => 'gif',        'time' => '1997-11-13',        'class' => 'dd',    ),    array(        'name' => '中国功夫',        'size' => '65',        'type' => 'jpe',        'time' => '1925-02-13',        'class' => 'yy',    ),    array(        'name' => '中国功夫',        'size' => '5',        'type' => 'icon',        'time' => '1967-12-13',        'class' => 'rr',    ),);print_r($arr);//注意：按照数字方式排序时 153 比 65 小$temp = sysSortArray($arr, "name", "SORT_ASC", "type", "SORT_DESC", "size", "SORT_ASC", "SORT_STRING");print_r($temp);?>
