Introduction to PHP two-dimensional array sorting and default natural sorting methods_PHP tutorial

PHP two-dimensional array sorting function, the default natural sorting, that is, sort sorting. Here you can specify multiple methods to sort by a certain value in the two-dimensional array. See the program comments below for details.

Copy code The code is as follows:

/**

* @function two-dimensional array natural sorting

* @author www.phpernote.com

* @param array $array Array to be sorted (two-dimensional)

* @param string key The key to sort by

* @param string order sorting method (SORT_ASC, SORT_DESC)

* @param string type sorting method (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 parameters 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;

}
