rtrim help

[neridaj]

Hey,

 

I don't understand why rtrim() isn't returning the referring page without the query string:

 

echo rtrim($_SERVER['HTTP_REFERER'], "?");

 

Thanks,

i don't think ? is a valide seconde parameter

$data = explode("?", $_SERVER['HTTP_REFERER']);
$referrer = $data[1];
echo $referrer;

 

explode is what you want, rtrim is for trimming extra characters at the end of a string, you just wanted to remove everything after the ?.

 

You may also want to checkout parse_url

 

@drisate: ? should work fine as long as you want to trim it and it is the last character of the string.

 

<?php
$trim = '"test string"?';
$trim = rtrim($trim, '?');
echo $trim;
die();
?>

Well that could get handy someday ;-)
