How to Grab your URL with PHP

Sometimes you want to grab your url from the web browser to do some thinking (maybe I want to display flowers on a random page, or want to display a lock if https is enabled). Here is some code that I have seen used over and over, and I have taken parts of it and used it for many a web project.

<?php
function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}
?>

now you can use the function

<?php
  echo curPageURL();
?>
