Need a regex to catch exact uri string dynamicaly

Question

Did you know if it's possible to catch exact string from uri with a regex ?

For exemple :

https://example.com
https://example.com/pizza

These two URIs are in the same text but I have to make a preg_replace for https://example.com only.

str_replace does not work here because it necessarily affects the second URI :P

Thanks for your time !

Edit : It's work with this expression : https://regex101.com/r/K7rgTh/6 But I need to catch inside html tags or not :P

Can you show what you have tried so far and how it fails in solving your problem. — Nigel Ren, Jun 26 '20 at 07:33

What comes _after_ the “exact string”? You probably want an expression that demands white space or a word boundary or something like that before and after the URL. — CBroe, Jun 26 '20 at 07:38
Exactly @CBroe These URI's are part of a CkEditor and therefore can be in any order with other words — Guillaume SOUILLARD, Jun 26 '20 at 07:51
Try to use this regex `https:\/\/example\.com(?=\s|$)`, know that there is no space after a uri — Illya, Jun 26 '20 at 08:02

You can use a fourth parameter like this:

preg_replace($search, $replace, $subject, 1);

This problem was solved on this posting Replace only first match using preg_replace.

I already tried that, the problem is that the text is in a CkEditor, suddenly, the link may not be in first position – Guillaume SOUILLARD Jun 26 '20 at 07:48

Use RegEx https:\/\/example\.com(?=\s|$), it will replace only https://example.com

Regex Explanation and Demo : https://regex101.com/r/K7rgTh/4 Usage:

preg_replace("/https:\/\/example\.com(?=\s|$)/i", "replacement", $text)

I think this will solve the problem

Nice ! But I need it to work inside html or not. Go here https://regex101.com/r/K7rgTh/6 As you can see, https://example.com is marked, but not
https://example.com

change it to `https:\/\/example\.com(?=\s|$|<)` – Illya Jun 26 '20 at 08:36
This works : ```https:\/\/example\.com(?=\s|$|<|")``` – Guillaume SOUILLARD Jun 26 '20 at 08:58

you can get your domain with http or https like this :



        if(isset($_SERVER['HTTPS'])){
            $protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
        }
        else{
            $protocol = 'http';
        }
        $url = $protocol . "://" . $_SERVER['HTTP_HOST'];
