本文实例讲述了php自定义函数实现二维数组排序功能。分享给大家供大家参考，具体如下：

/**作用: 二维数组排序函数,支持多键名排序

* 返回: 排序好的数组

* 使用: array_msort(数组,需要排序的键名,排序方式);

* 例子: array_msort($cflist,"chapter_orderid","SORT_ASC");

* array_msort($arr,"name","SORT_ASC","type","SORT_DESC","size","SORT_ASC","SORT_STRING");

*/

function array_msort($ArrayData,$KeyName1,$SortOrder1 = "SORT_ASC",$SortType1 = "SORT_REGULAR") {

if(!is_array($ArrayData)) {

return $ArrayData;

}

// 获取参数数量.

$ArgCount = func_num_args();

// 排序,并放置到SortRule数组

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;

}

希望本文所述对大家PHP程序设计有所帮助。
