Regex not getting whole link at special characters

Question

I am using this code:

$string = preg_replace(\"~(?!(?:https?://(?:www\\.)?|www\\.)(?:youtube\\.com)(?:https?://(?:www\\.)?|www\\.)[\\w./=?#-]+~i\", \'

        

Answer 1

Also I'm trying to account for punctuation at the end of a URL (so that we don't include it).

<?php

$string = "This works http://upload.wikimedia.org/wikipedia/commons/f/f2/Bill_Clinton%2C_Yitzhak_Rabin%2C_Yasser_Arafat_at_the_White_House_1993-09-13.jpg. This one should fail http://www.youtube.com/v/adlskdfjasopie. Although this one should fail as well http://youtu.be/adlkajdaslk.";

$string = preg_replace("~(?!(?:https?://(?:www\.)?|www\.)(?:youtu))(?:https?://(?:www\.)?|www\.)[^\s]+[^.!?,\<\]\[\)(]~i",'<a href="$0">$0</a>',$string);


?>

output

This works <a href="http://upload.wikimedia.org/wikipedia/commons/f/f2/Bill_Clinton%2C_Yitzhak_Rabin%2C_Yasser_Arafat_at_the_White_House_1993-09-13.jpg.
