[PHP] fast question about session_start

[Romulo Roberto Pereira]

Hello!

Two scripts: first.php and second.php

I am a little bit confused... since I session_start() in first.php, I will need to 
session_start() in second.php also?

first.php

<?
session_start();

session_register ("data01");

header("Location: second.php")

?>

thank you,

Rom
