PHP multidimensional array PHP custom functions for two-dimensional array sorting function

In this paper, we describe the function of PHP custom function for two-dimensional array sorting. Share to everyone for your reference, as follows:

/** function: Two-dimensional array sorting function, support multi-key name sort * Return: sorted array * Use: Array_msort (array, key name to sort, sort by); * Example: 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, $KeyName 1, $SortOrder 1 = "Sort_asc", $SortType 1 = "Sort_regular") {if (!is_array ($  Arraydata) {return $ArrayData;  }//Gets the number of parameters.  $ArgCount = Func_num_args ();    Sorted and placed into the Sortrule array for ($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;}
