PHP http_build_url() et PECL Install

Il y a un travail autour de. Si vous ne voulez pas ou ne pouvez pas utiliser PECL, alors il existe une méthode, mentionné sur le php.net les commentaires, qui est une méthode alternative:

if (!function_exists('http_build_url'))

define('HTTP_URL_JOIN_QUERY', 4);           //Join query strings
define('HTTP_URL_STRIP_USER', 8);           //Strip any user authentication information
define('HTTP_URL_STRIP_PASS', 16);          //Strip any password authentication information

define('HTTP_URL_STRIP_ALL', 1024);         //Strip anything but scheme and host
//Build an URL
//The parts of the second URL will be merged into the first according to the flags argument.
