The code below allows you to sort an array_A following array_B keys order, original keys and values remain associated.
<?
//main function
Function SortArrayAKeysLikeArrayBKeys(&$TheArrayToSort){
uksort($TheArrayToSort,"SortArrayAKeysLikeArrayBKeys_cmp");
}
//the custom compare function
Function SortArrayAKeysLikeArrayBKeys_cmp($a,$b){
global $TheArrayOrder;
$PosA=KeyPosInArray($a,$TheArrayOrder);
$PosB=KeyPosInArray($b,$TheArrayOrder);
if ($PosA==$PosB){return 0;}else{return ($PosA > $PosB ? 1 : -1);}
}
//where is my key in my array
Function KeyPosInArray($Key,$Array){
$i=0;
$Pos=99999999;
if($Array){
foreach($Array as $K => $V){
$i++;
if($K==$Key){
$Pos=$i;
break;
}
}
}
return $Pos;
}
//the array you want to sort
$AnyArrayToSort['age']='19';
$AnyArrayToSort['ville']='rennes';
$AnyArrayToSort['website']='kik-it.com';
$AnyArrayToSort['region']='bretagne';
$AnyArrayToSort['code_postal']='35200';
$AnyArrayToSort['Nom']='Fred';
//the array with the correct keys/values order
$TheArrayOrder['Nom']='Whatever';
$TheArrayOrder['age']='Anything';
$TheArrayOrder['region']='What u want';
$TheArrayOrder['ville']='Something';
$TheArrayOrder['code_postal']='Nothing';
//before sort
print_r($AnyArrayToSort);
echo "<br>";
//we sort
SortArrayAKeysLikeArrayBKeys($AnyArrayToSort);
echo "<br>";
//after sort
print_r($AnyArrayToSort);
?>
Will print :
Array ( [age] => 19 [ville] => rennes [website] => kik-it.com [region] => bretagne [code_postal] => 35200 [Nom] => Fred )
Array ( [Nom] => Fred [age] => 19 [region] => bretagne [ville] => rennes [code_postal] => 35200 [website] => kik-it.com )
The keys not listed in the $TheArrayOrder will appear at the end of your sorted array (only if Key Pos < 99999999 ;o)
