Question

what is the best preg_replace to create an SEOed text to be used in uri ??

i mean like if we had this uri http://t.com/SOME RANDOM $#@ TEXT _ + ?/ =\ , what is best preg_replace expression to clean it up ?

Thank you .

EDIT : assuming you have multiple languages in the random text language ??

Answer 1

Do you mean a slug?

Slug('SOME RANDOM $#@ TEXT _ + ?/ =\\'); // some-random-text

For that this should be enough:

function Slug($string, $slug = '-')
{
    return strtolower(trim(preg_replace('~[^0-9a-z]+~i', $slug, $string), $slug));
}
