Twitter like profile linking

[doddsey_65]

im trying to link a profile if it is prefixed with an @ symbol. I have tried this but it doesnt work as i thought it wouldnt.

 

$content = preg_replace('|@(.*?)|', profile_link('$1'), $content);

function at_name($content)
{
    $pattern = '/\@([a-zA-Z0-9._-]+)/';
    $replace = '<a href="'. BASE_URL . 'u/\1">@\1</a> ';
    
    return preg_replace($pattern, $replace, $content);
}

echo preg_replace("#\@([a-z0-9\_]+)#i", '<a href="http://www.twitter.com/$1">@$1</a>', $text);

You can replace the twitter.com with anything, such as your function that generates the URL.
