Question

I’m trying to write a code library for my own personal use and I’m trying to come up with a solution to linkify URLs and mail links. I was originally going to go with a regex statement to transform URLs and mail addresses to links but was worried about covering all the bases. So my current thinking is perhaps use some kind of tag system like this:

l:www.google.com becomes http://www.google.com and where m:[e-mail] becomes [e-mail].

What do you think of this solution and can you assist with the expression? (REGEX is not my strong point). Any help would be appreciated.

Answer 1

Maybe some regex like this :

$content = "l:www.google.com some text m:[e-mail] some text";
$pattern = '/([a-z])\:([^\s]+)/'; // One caracter followed by ':' and everything who goes next to the ':' which is not a space or tab
if (preg_match_all($pattern, $content, $results))
{
    foreach ($results[0] as $key => $result)
    {
        // $result is the whole matched expression like 'l:www.google.com'
        $letter = $results[1][$key];
        $content = $results[2][$key];

        echo $letter . ' ' . $content . '<br/>';
        // You can put str_replace here
    }
}
