Introduction to PHP two-dimensional array sorting and default natural sorting method

PHP two-dimensional array sorting function, the default natural sort, that is sort. Here you can specify a number of methods to sort by a value in a two-dimensional array, depending on the program note below.

/** * @function A two-dimensional array of natural sort * @author www.phpernote.com * @param array $array need to sort arrays (two-dimensional) * @param string key depends on which key  Sort * @param String order Sort method (Sort_asc,sort_desc) * @param string type Sort by (sort_regular,sort_numeric,sort_string) *   @return Array sorted array. */function Phpsortarray ($array, $key, $order = "Sort_asc", $type = "Sort_regular") {if (!is_array ($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). ', $array);      eval ($EvalString);  return $array; }
