Regex for dropping http:// and www. from URLs

Question

I have a bunch of urls like these.

  $urls = array(
    \'https://site1.com\',
    \'https://www.site2.com\',
    \'http://www.site3.com\',
    \'https://sit         


        

Answer 1

/^(https?:\/\/)?(www\.)?(.*)\/$/i

And use what's on $3. Or, even better, change the first two parentheses to the non-capturing version (?:) and use what's on 1.
