Php Problem T_ENCAPSED_AND_WHITESPACE Need Help!!!

I have this line of code:

function smile($aurl)
...
...
...
header("Location: smile($_GET['url'])");

Code (markup):

and it keeps on giving me this error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/admin/domains/site.com/public_html/test.php on line 23

Code (markup):

What am I doing wrong, can someone help me rewrite the code to make it work?

 

I also tried this:

function smile($aurl)
...
...
...
$aurl= $_GET['url'];
$linksmile=smile($aurl);
header("Location: $linksmile");

Code (markup):

and I got this:

Warning: Cannot modify header information - headers already sent by (output started at /home/admin/domains/site.com/public_html/test.php:2) in /home/admin/domains/site.com/public_html/test.php on line 64

Code (markup):

 

whats in the "...."'s?

and what are you trying to do?

(Something with a function to redirect based on a link variable?)

 

Yes, the ... are the rest of the script, this is one part of my encryption script, I really can't share the rest because there would not be a point of encryption if I shared the rest.

 

u cant have single quotes in double quotes

try

header("Location: smile($_GET[url])");

PHP:

 

I believe your headers must be the first line in your page before any HTML
