PHP: remove all characters from string after X occurrences of a character

Question

I'm trying to remove all the characters of a string AFTER a character appears 4 times, in this case the fourth appearance of character "/".

So if I have a string like this:

https://www.imbd.com/zenithasianfancyfood/posts

I want to get something like:

https://www.imbd.com/zenithasianfancyfood/

Scroll down, look at Chris Eberle's answer, it's so much simpler than the first two. — Nic3500, Sep 20 '20 at 01:14

Here we go, We can achieve this using explode function

  <?php
    $url = 'https://www.imbd.com/zenithasianfancyfood/posts';

    echo get_before_url_on_particlar_slash($url,4);
    
    function get_before_url_on_particlar_slash($url,$slash_position)
    {
        if(isset($url,$slash_position) && !empty($url))
        {
            $m = explode('/',$url);
            $s = '';
            foreach ($m as $k => $v)
            {
                if($k == $slash_position)
                {
                    break;
                }
                
                if($k == 0)
                {
                    $s .= $v.'//';
                }
                else
                {
                    $s .= $v.'/';
                }
                
            }
        }
        
        return rtrim($s,"/");
    }
?>

If you want last slash then you can remove rtrim() function – Siddhartha esunuri Sep 20 '20 at 04:59 — Siddhartha esunuri, Sep 20 '20 at 04:59
