Sometimes, you might want to get the current page URL that is shown in the browser URL window. For example if you want to let your visitors submit a blog post to Digg you need to get that same exact URL. There are plenty of other reasons as well. Here is how you can do that.
Add the following code to a page:
<?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;
}
?>
You can now get the current page URL using the line:
<?php
 echo curPageURL();
?>
for example, if you want to check the current url is the same as other one or not, you can use it, if they ar the same, show one thing, if not, show another, the code is as follows:
<?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;
}
?>
<?php
 echo curPageURL();
$cururl=curPageURL();
?>
<br>
<?php if (‘http://kingphp.com/’==$cururl)echo ‘Kingphp’;
else echo ‘Welcome to Kingphp’; ?>
