php POST variables

chrisleon

I have written a little script that a user can be redirected to a url of there choice. Here is what it looks like

<?php
$url = $POST["url"];
if($url==""){
$url=$SERVER["HTTP_REFERER"];
}
elseif(!ereg("^{http:\/\/",$url)&&!ereg("^https:\/\/",$url)} &&!ereg("^ftp:\/\/",$url)){
$url="http://".$url;
}
header("Location:_$url");
?>

But when the user clicks submit, it come up with a parse error
T_CONSTANT_ENCAPSED_STRING

I have never seen this error, and I can not find a single page out there that can tell me what this error pertains to. It is supposibly on line 3, but I don't see anything wrong with the code. The only thing I can think of is the 'register globals' setting is turned on, and it may interrupt the POST variables. Please Help!

thanx in advance

i found this on it:

http://me.in-berlin.de/doc/phpdoc/html/tokens.html
->http://me.in-berlin.de/doc/phpdoc/html/language.types.string.html#language.types.string.syntax

maybe its because youre using $POST["something"] and not $POST['something'] ????

try it

Your text editor is inserting an under score (_) as a space character which is causing the error.

I copied the code and got the same error on line 3 but removed the _'s and it was fine.

I went through the whole script and removed all the white spaces, and there was no underscores that were visible to me, but again, I removed all the spaces, and it worked. I appreciate the advice.
