note 16213 added to function.array-intersect

someone might need to generate the parameter head of array_intersect in runtime (eg: not always the same number of arrays, or the same arrays...). i was looking and asking for a solution to this problem but noone could really give me anything more efficent (and shorter) than this one: //these are your arrays you want to intersect: $arr1=array("A","B","C","D","E"); $arr2=array("D","E","C","G","H","I","J"); $arr3=array("A","D","E","G","H","K"); $arr4=array("E","B","H","D","K","L"); //solution: D E //this is your function parameter-head, you can generate this however you want: $params="arr1,arr2,arr3,arr4"; $arr_arr=explode(",",$params); $anz=sizeof($arr_arr); for ($i=0;$i<$anz-1;$i++ ) { ${$arr_arr[$i+1]}=array_intersect(${$arr_arr[$i]},${$arr_arr[$i+1]}); }//for $intersect=${$arr_arr[$anz-1]}; foreach ($intersect as $elem ) { echo $elem." "; }//foreach maybe someone needs this, ... maybe not, maybe even you know a better and shorter way (let me know!!). cya, folks! lectrix. -- http://www.php.net/manual/en/function.array-intersect.php http://master.php.net/manage/user-notes.php?action=edit+16213 http://master.php.net/manage/user-notes.php?action=delete+16213 http://master.php.net/manage/user-notes.php?action=reject+16213
