Delete last character of string (if exists)

I have a string containing some text, the last character might (might) be a slash, which I don't want. How do I remove that, if it exists?

Is this the "correct" way?

if(substr($str, -1) == "/") $str = rtrim($str, '/');

Use rtrim with two parameters (string to be trimmed, character to be removed)

For your case:

rtrim($str, '/');

In my case i need to delete severalsymbols like "1." or "2.", etc. Here's code:

/**
 * @param string $string
 *
 * @return string
 */
private function cutNumbers($string)
{
    for ($i = 1; $i < 20; $i++) {
        $position = strpos($string, $i . '.');

        if ($position === 0) {
            $string = substr($string, 2);
        }
    }

    return $string;
}

PS: I know there is better solution but anyway - hotfix will help someone.

This replaces the last character of a url if it is a '/'

concat(LEFT(url, LENGTH(url)-1),replace(right(url, 1),'/',''))

if you have a string $string try using

substr_replace($string ,"",-1);

or

substr($string, 0, -1);

or

mb_substr($string, 0, -1);

it will remove the last character from $string.

Use rtrim without a condition, it's shorter and probably faster as well. The added if is noise and doesn't offer anything.
