Question About Array

["saeedos" <saeedos@xxxxxxxxx>]

Hi all ,
i have this Array :
$country=array("USA","KSA","SYR","GER","EGY","JPA","CHA","PAK");

// I want the output of this array looks like this :

USA  KSA  SYR
GER  EGY  JPA
CHA  PAK


i know it's can be done in Nested for loops , but i don't know how .

thanks
