url encode和str_replace

Question

I am trying to encode a sites current RFC 3986 standard and using this function:

function getUrl() {

      $url  = @( $_SERVER["HTTPS"] != 'on' ) ? 'http://'.$_SERVER["SERVER_NAME"] :  'https://'.$_SERVER["SERVER_NAME"];
      $url .= ( $_SERVER["SERVER_PORT"] !== 80 ) ? ":".$_SERVER["SERVER_PORT"] : "";
      $url .= $_SERVER["REQUEST_URI"];

      $entities = array('%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D');
      $replacements = array('!', '*', "'", "(", ")", ";", ":", "@", "&", "=", "+", "$", ",", "/", "?", "%", "#", "[", "]");

      return str_replace($entities, $replacements, urlencode($url));

    }

The URL added : http://localhost/test/test-countdown/?city=hayden&eventdate=20160301 Returns: http://localhost/test/test-countdown/?city=hayden&eventdate=20160301 Not encoded with the // and & replaced

Answer 1

If you want encode an URL (not a site) in this format:

http%3A%2F%2Flocalhost%2Ftest%2Ftest-countdown%2F%3Fcity%3Dhayden%26eventdate%3D20160301

use the built-in php function rawurlencode( $url ).
