The PHP IP Guide

This guide shows you common practices to convert IPv4- and IPv6-Addresses into their binary representation.

Who is responsible for this ?

This guide has been written by Matthias Kaschubowski, a autodidactical software developer from germany with about 14 years of practice converting coffee to code. He works in his free time as a php evangelist on a lot of platforms ( last shown as tr0y on php.de, a german PHP related forum and as himself as an adminstrator at the largest PHP-related facebook group ).

If the input is utf8-encoded, might use unicode regex to match/strip invisible control characters like e2808e (left-to-right-mark). Use u (PCRE_UTF8) modifier and \p{C} or \p{Other}.

Strip out all invisibles:

$str = preg_replace('/\p{C}+/u', "", $str);

  • Who is going to use it?
  • How are they going to use it?
