$k= array('22','26','33','36','37','45','51','53','54' ,'55','60','62','63','64','65','68','69','71','73' ,'76','79','80','82','83','87','89','91','93','94' ,'98','99','112','121','127','177','179','182','18 5','186','187','189','192','193','205','206','212' ,'213','217','218','219','222','223','227','229',' 231','236','239','240','241','242','245','246','24 9','250','254','255','257','259','263','264','266' ,'267','272','273','274','278','279','282','283',' 285','286','287','288','291','292','294','295','29 8','300','302','307','308','314','324','328','331' ,'334','340','342','344','345','348','356','358',' 364','366','370','371','372','373','375');

şöyle iki adet arrayım var..

$katlarda ki 1. indis olan ile $k daki 1. indisi eşitliycem kafa durdu iyice
Örn=> '532', '22', '423', '26'

bu şekilde nasıl listelerim?

her ikisinin aynı adette olduğunu varsayıyorum
en basiti
$c = count($katlar);
$yenidizi = array();
for($i = 0; $i < $c;$i++){
$yenidizi[] = $katlar[$i];
$yenidizi[] = $k[$i];
}

@darness; teşekkürler
