PHP Replace Dynamic url from string

Question

I have a robot voice that turns sentences into spoken mp3 files. But the robot voice can't pronounce urls so I want to filter the urls out.

I got dynamic strings coming in that can look like this: "Hello my name is Jeffrey" This works fine but strings can also contains urls and looks like this: "Hello http://wwww.google.nl is a very nice site." or "Hello how are you doing https://soundcloud.com/theforeignexchangemusic/zo-manmade-sampler …" or "Take a look at this picture http://instagram.com/p/xPiSn8Pmli/ " And so on

If a string contains an url I want to replace the url with a word. Does anybody know a good way of doing this? Because the strings are dynamic (Length, content and location) I find it very hard to do. If someone has a good idea please let me know! Would be appreciated a lot.

You can use a regular expression that searches for URLs and using said regular expression, replace the URL with a word of your choice. — Anil

Well, I still understand your question properly. So, if it is coming like "Hello wwww.google.nl is a very nice site." then you want it to be like this "Hello Google is a very nice site."? — iSaumya

Your best bet is to use RegEx to parse the strings to see if URLs come up.

Using RegEx to then find the base domain and then vocalize that.

/^(https?://)?([\da-z.-]+).([a-z.]{2,6})([/\w .-])/?$/ Regex for URLs

If somebody is looking for exactly the same thing here is a working example.

<?php
$hallo = 'Hey it works. http://onderbroekenlol.nl something behind the url.';
$str = preg_replace("/(?:https?:\/\/)?(?:[\w]+\.)([a-zA-Z\.]{2,6})([\/\w\.-]*)*\/?/", "a website", $hallo);
print $str;
?>

[\w] is more simply written as \w. Inside of a character class, . does not need to be escaped. If you have a pattern with / in it, it is simpler to use a unique character as the pattern delimiter such as ~ so that you don't have to escape all of the / characters.
