[SOLVED] Does session_start have to be called inside a function?

[therealwesfoster]

If in a function I'm going to be working with sessions, does session_start() need to be called in the function? Or global $_SESSION?

 

Please let me know

session_start() needs to be called before you use a session variable.  Doesn't matter if it's inside or outside of a function.  session variables are already global.  If you assign something to a session variable without (or before) calling session_start(), it will act like a normal global variable for that page, but will not persist to other pages.

Thanks for the reply

 

I have a global header in which I call session_start(). Should I call this again in a function (later down the page) or no?

If this so called global header has already been included there would be no need to include it again.

Ok, so this simple script should output "test"

<?php
session_start();
$_SESSION['test'] = 'test';

function show(){
  return $_SESSION['test'];
}

echo show();
?>

Instead of c/p'ing it here and asking if it will work, you could always c/p it to a test.php and run it and find out.

1. I didn't copy, I wrote it real quick.

2. I didn't ask if it would work, I just made a statement before marking the topic as solved.

hmm I coulda swore I saw a question mark in there, hence the statement. My bad.  But for argument sake, for #1, I meant it in a more generic sense.  As in, if you're going to take the time to put it in one place, why not just put it in another place, click the proverbial run button and see what happens?
