The code below removes "www.", etc. from the beginning of websites that are entered into a database. It works great.
Is there a way I could use similar code to remove a forward-slash from the tail-end of a website that is entered into the same database?
$remove_array = array('http://www.', 'http://', 'https://', 'https://www.', 'www.');
$site = str_replace($remove_array, "", $_POST['site']);
You can pass a string of characters that you want trimmed off of a string to the trim family of functions. Also, you could use rtrim to trim just the end of the string:
$site = rtrim($site, "/");
$site = preg_replace('{/$}', '', $site);
This uses a relatively simple regular expression. The $ means only match slashes at the end of the string, so it won't remove the first slash in stackoverflow.com/questions/. The curly braces {} are just delimiters; PHP requires matching characters and the front and back of regular expressions, for some silly reason.
Simplest method:
$url = rtrim($url,'/');
John was the first and I think his solution should be preferred, because it's way more elegant, however here is another one:
$site = implode("/", array_filter(explode("/", $site)));
Update
Thx. I updated it and now even handles things like this
$site = "///test///test//"; /* to => test/test */
Which probably makes it even cooler than the accepted answer ;)
Is that what You want?
$url = 'http://www.example.com/';
if (substr($url, -1) == '/')
$url = substr($url, 0, -1);
You could have a slash before the question mark sign and you could have the "?" sign or "/" in the parameters (.com/?price=1), so you shouldn't delete this every time. You need to delete only the first slash "/" before the question mark "?" or delete the last slash "/" if you have no question marks "?" at all.
For example:
would be
And
https://money.yandex.ru/to/410011131033942/
would be
https://money.yandex.ru/to/410011131033942
The PHP code for this would be:
if(stripos($url, '?')) {
$url = preg_replace('{/\?}', '?', $url);
} else {
$url = preg_replace('{/$}', '', $url);
}
The most elegant solution is to use rtrim().
$url = 'http://www.domain.com/';
$urlWithoutTrailingSlash = rtrim($url, '/');
EDIT
I forgot about rtrim();
You could also play around parse_url().
$new_string = preg_replace('|/$|', '', $string);
rtrim()?Perhaps a better solution would be to use .htaccess, but php can also do it with something like this:
<?php
header('location: '.preg_replace("/\/$/","",$_SERVER['REQUEST_URI']));
?>
