require_once

[jogurt1]

Hi Guys,

 

I have a quick question concerning 'require_once'.

 

Lets say I have 2 files, file 1 and file 2.

 

In file 1, I have a 'require_once(file 2)'.

 

Does that mean that file 2 can access variables in file 1?

Yes, as long as require_once() is called before the variables are referenced.

1.php

<?php
echo $foo; // $foo is not defined
require_once '2.php';
echo $foo; // prints "pterodactyl!"
?>

 

2.php

<?php
$foo = 'pterodactyl!';
?>

Ok great thanks! So the following should work then:

 

1.php

<?php
echo $foo = "lol";
require_once '2.php'; //prints "lol"
?>

 

2.php

<?php
echo $foo;
?>

<?php
$foo = "lol";
require_once '2.php'; //prints "lol"
?>

 

That is how you should do it.
