[SOLVED] can't print variable written in the page ling

[SZero]

hi every1..

 

i posted a topic lately on how to disable debugging cause of the NOTICE message..

anyway i asked this cause when i was trying to print a variable sent in the link it shows this message and doesn't prin it..

 

to make it more simple, there's a page called Index.php with this code in it:

 

<?

print "$extra";

?>

 

i call the page like this:

 

www.MyDomain.com/index.php?extra=Hii

or

www.MyDomain.com/?extra=Hii

 

before an error appeared (NOTICE: Undefined Variable extra....) and it didn't print, now i disabled debugging, no errors show but still doesn't print..

 

any help plz.. ty

Because it's not set.

You need:

$extra = $_GET['extra'];

 

Also, don't put quotes around a variable, you're making PHP work harder.

print $extra;
