[SOLVED] when/how do variables die

[Yeodan]

Say I have this:

 

index.php

<?php
include 'something.php';
echo $name;

 

something.php

<?php
$name = "Yeodan";
?>

 

Will $name still be defined in index.php where I used it?

How can do I remove the variable?

 

Also are the <?php ?> tags needed in the something.php if I already have them in the index.php?

Yes

unset($name);

Yes

In short, yes but only after the point where the file was included.

 

If register globals is turned on then yes, it would be carried over from the include file.

 

This is how it used to be set up but caused a LOT of problems (mainly security) so globals are turned off by default.

 

Variables die when a script terminates or when you kill them manually.

 

Here's the "Matrix" question... where do the contents go when they die???

 

EDIT: Edited first line of my response.

To the OP, I'd ignore Yesideez's reply, Mark Baker hit the nail on the head.

[Yesideez]

I would ignore me as well - I didn't read the question properly.

It happens.

The variable name is normally buried, or cremated and the ashes scattered over the CPU. The variable value goes to the great stack dump in the sky.
