Copy CodeThe code is as follows:

* @param string key depends on which key to sort

* @param String Order Sort method (Sort_asc,sort_desc)

if (!is_array ($array) | | Empty ($ $array)) {

return $array;

}

$ArgCount =func_num_args ();//Returns the number of arguments passed to the currently defined function

for ($I =1; $I < $ArgCount; $I + +) {

$Arg =func_get_arg ($I);

if (!eregi ("SORT", $Arg)) {

$KeyNameList []= $Arg;

$SortRule []= ' $ '. $Arg;

}else{

$SortRule []= $Arg;

foreach ($array as $Key = = $Info) {

foreach ($KeyNameList as $KeyName) {

${$KeyName}[$Key]= $Info [$KeyName];

}

}

$EvalString = ' Array_multisort ('. Join (",", $SortRule). ', $array);
