Strip last / off URL using preg_replace ?

overla

Hello all,

I have been struggeling to fix a preg_replace issue i have, and i wonder if someone here might be able to help please?

I am trying to strip the final / off my URL when i feed the URL into a search form i have. Everything else works perfectly, it's just this final / on the end of my URL which is ruining things for me. I'm not sure how to strip it, any advice greatly appreciated.

I tried putting in $drop = strrchr($last, ' ');
but this doesnt change anything. I have no idea where i should put it, or if it is correct, i have just been hacking away cluelessly at this code for days and cant resolve it.

Thanks in advance for any help whatsoever - even if it is to tell me that this is not possible.

Here is the part of my code:

<?php
$search_term = substr($SERVER['REQUEST_URI'],1);
$search_term = urldecode(stripslashes($search_term));
$find = array ("'.html'", "'.+/'", "'[-/]'") ;
$replace = " " ;
$search_term = trim(preg_replace ( $find , $replace , $search_term ));
$search_term_q = preg_replace('/ /', '%20', $search_term);
$full_search_url = $search_url . $search_term_q;
?>
<p>Searching for <a href="<?php echo $full_search_url; ?>"><?php echo $search_term; ?></a></p>

i don't see any attempts in that code to remove any trailing backslashes. maybe you should try reading about php's string manipulation functions:

I think this line is meant to remove Bslash[/B]
It will not work, but somebody can fix it.
I can not, I dont know how to target last character in a string.

$search_term_q = preg_replace( '/ /',  '%20',  $search_term );

can you just use trim() function to trim it off?
$url=trim($url, "/");

<?php

// Only use if you've made sure last Character is /
$newpath = substr_replace("C:/Documents and Settings/", "", -1, 1);

?>

this line does NOT replace backslashes with anything:

$search_term_q = preg_replace( '/ /',  '%20',  $search_term );

it replaces spaces with %20

like i said, maybe you should do some reading about the string replacement functions. then you would know that the first arg to preg_replace has to be a regular expression.

RTFM.

Dont use preg_replace(), use [man]rtrim/man.

Laserlight, thankyou - after 2 days i finally got it! thanks to your rtrim advice.

I almost had it with preg_replace, but i was putting it in the wrong place:

$search_term = substr($SERVER['REQUEST_URI'],1);
$search_term = urldecode(stripslashes($search_term));
$search_term = rtrim($search_term, '/');
$find = array ("'.html'", "'.+/'", "'[-/]'") ;
$replace = " " ;
$search_term = trim(preg_replace ( $find , $replace , $search_term ));
$search_term_q = preg_replace('/ /', '%20', $search_term);
$full_search_url = $search_url . $search_term_q;
