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> "
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);
preg_replace() works with $yourString being an array of strings (returns an array).This regex should do the trick:
$s= "Text: Here's 2 free bonuses. http://blablabla.blabla/blabla and some more text";
$s2= preg_replace('~(http://\S+)\b~', '<a href="$1">$1</a>', $s);
var_dump($s2);
