Question

How can I extract the HTTP from this text?

"Text: Here's 2 free bonuses. http://blablabla.blabla/blabla "

But the URL can also be another one.

Finally

After I have the array, which contains usually just one URL, how can I add it to the above text exactly at the same position? But with HTML tag <a>

The results should look something like this:

"Text: Here's 2 free bonuses. 
<a href='http://blablabla.blabla/blabla'>http://blablabla.blabla/blabla</a> "

Answer 1

You can do that using regular expression, and more precisely preg_replace(). The matching expression can be something like :

$pattern = 'http://[a-zA-Z0-9\.\-/]+';

Of course, you can refine it for more precise matching, but this should do the trick. If you want to play with regex, have a look at regexpal, it’s a great tool for testing. Then, you can perform the replace ($0 corresponds to the whole matched string :

preg_replace($pattern, '<a href="$0">$0</a>', $yourString);
