Detecting url in a text

Hi guys,

I want to do something like youtube where when you type a url in the description it will automatically turn it into a hyperlink.

Any advice on getting started?

 

try this:

function parse_links($str)
{
$str = str_replace('www.', 'http://www.', $str);
$str = preg_replace('|http://([a-zA-Z0-9-\./]+)|', '<a href="http://$1">$1</a>', $str);
$str = preg_replace('/(([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6})/', '<a href="mailto:$1">$1</a>', $str);
return $str;
}
?>
<span id="more-50"></span>

Code (markup):

 

Thanks. I'll give it a try.

 

That won't work if they post a url with just http:// or with http://www. because the http://www. will turn into http://http://www.

try this...

$str = $variable; //where $variable is the variable of the post or description
$str = str_replace('http://', 'www.', $str);
$str = str_replace('http://www.', 'www.', $str);
$str = str_replace('www.', 'http://www.', $str);
$str = preg_replace('|http://([a-zA-Z0-9-\./]+)|', '<a href="http://$1">$1</a>', $str);
$str = preg_replace('/(([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6})/', '<a href="mailto:$1">$1</a>', $str);
$str = trim($str);
echo "".$str.""; //prints the variable of the post with the new link added.

Code (markup):

Only problem is that if they don't have www. or http:// or http://www. or if they have https:// or another link it will not work sorry I can't test it at the moment I am on vacation and using my phone...don't tell.

 

AustinQPT You are right, good code btw

This is a nice code. it took me 5 minutes to add it to my script. AustinQPT definitely saved me a lot of hours.
