ok, now the only problem is that if a user just enter "http://www.example.com" the way my script runs, it enter a <br /> after each line of input. and when a link is entered it displays it a as
ex.
http://www.example.com
/>
and the link is "http://www.example.com<br"
how can i fix this?

also doing the url first then adding a space and putting text make the url functional but it cuts out the space and make the text right next to the link text with no space...

If i understand correctly, the idea is to take some user input and create <a> elements for each valid url in it.
Try this regexp :
1 2 3
<?php $input = preg_replace("/(www\.|http:\/\/)([^\s]+)/", '<a href="http://$1$2" target="_blank">$1$2</a>', $input); ?>

if I want to see only name of the domain in the link?
ex.
url = 'http://www.site.com';
<a href="http://www.site.com">site</a>

This snippet corrects a slight syntax error in shtruc's snippet (link hrefs would be reproduced as "http://http://example.com"). It assumes that URLs are not already in link tags (you've cleaned any html a user may have entered beforehand), and also takes the liberty of trimming the link text to 68-ish characters.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
<?php $input = <<<EOF http://www.example.com/ http://example.com www.example.com http://iamanextremely.com/long/link/so/I/will/be/trimmed/down/a/bit/so/i/dont/mess/up/text/wrapping.html EOF; $output = preg_replace("/(http:\/\/|(www\.))(([^\s<]{4,68})[^\s<]*)/", '<a href="http://$2$3" rel="nofollow">$2$4</a>', $input); /* This results in the following links: <a href="http://www.example.com/" rel="nofollow">www.example.com/</a> <a href="http://example.com" rel="nofollow">example.com</a> <a href="http://www.example.com" rel="nofollow">www.example.com</a> <a href="http://iamanextremely.com/long/link/so/I/will/be/trimmed/down/a/bit/so/i/dont/mess/up/text/wrapping.html" rel="nofollow">iamanextremely.com/long/link/so/I/will/be/trimmed/down/a/bit/so/i/do</a> */ ?>

Actually I found one issue ... if the url is ending with a "dot" or "comma", e.g.: visit www.example.com, now.
The comma messes things up ... as it becomes http://www.example.com,/
Is there a solution to "characters in the end of the url"? It's all that lacks in this excellent snippet ...
Thanks!

Hi there,
Just stumbled upon this thread and hoping somone can help me out. I have the oposite problem. I need to remove the code from around the url which is coming out of the db.
I need to be left with only the www.asdf.com towards the end of the line of code between the "> and the < /a>
Any ideas how to do this?
Thanks
1
<a href="http://www.asdf.com" target="_blank">www.asdf.com</a>

To not include comma's just need to change the the end of url from \s to (\s|,) like this:
1 2
$output = preg_replace("/(http:\/\/|(www\.))(([^(\s|,)<]{4,68})[^(\s|,)<]*)/", '<a href="http://$2$3" rel="nofollow">$2$4</a>', $input);
im not quite sure where to start. i want to have a php script that looks at a users input and looks for a valid link (ex. http://www.example.com) and if url is in that text replace it with <a href="URL">URL</a>
