Automatic Url Activation in Text HELPP Soo HArd

[Berone]

I am trying to make it so that in a post... Whenever someone posts a link, it is activated... for example...

 

 

 

Go to http://www.link.com  to see my site

 

would change to

 

 

Go to <a href='http://www.link.com'>http://www.link.com</a> to see my site.

 

 

I can't figure out how to do this, and have been looking through the php functions to find the right one to use... Can anyone help me?

This site does it already, see how it automatically made my url a link?

Try it with RegEx:

<?php
   $content = 'Hello! Visit my link: http://www.blubb.com www.link.com www.ahoi.com';
   $content = preg_replace('{(http://www\.[\w\d\.:/]+)}', '<a href="$1">$1</a>', $content);
   $content = preg_replace('{(?<!http://)(www\.[\w\d\.:/]+)}', '<a href="http://$1">$1</a>', $content);
   echo $content;
?>

Heh I wrote a different one...

 

<?php
$url = "http://www.some-url.com";
$url = preg_replace ("%(http://www.?[A-Za-z-]*.?[A-Za-z-]{1,5})%", "<a href='$1' title='$1' />$1</a>", $url);
print ($url);
?>

 

I like your use of \w\d  - you also need to allow for a hyphen in the character range though.

 

Regular expressions rule

but what if there's a link like www.foo.com ?

<?php
$url = "http://www.some-url.com";
$url = preg_replace ("%([http://]*[www]{3}.?[A-Za-z-]*.?[A-Za-z-]{1,5})%", "<a href='$1' title='$1' />$1</a>", $url);
print ($url);
?>

Actually this is a bit better:

 

%((http://)?(www)\.?[A-Za-z-]*\.?[A-Za-z-]{1,5})%
