php - Not sure the loop I need to use every two variables -

i have problem have array $user.

i have $_session['players'] has total amount of $user.

i need function can take user1 , 2 , use them. move on user3 , 4 , use them, , on.. until have used players. total $user[$i] players-1.

anyone have solution this? thanks

would suit needs? requires there number of players work though, unless stick in check odd numbers:

for ($i = 0; $i < $_session['players']; $i += 2) {     $usera = $user[$i];     $userb = $user[$i + 1];      // things $usera , $userb variables... }
