Hey Experts!!

I need to have a conditional statement based on a URL.  But, I only need the www.mydomain.com part of the URL.  Anything pre or post that part is irrelevant.  

I'm poking around in PHP so please be gentle.  Any and all help is appreciated!!

And then tell us what kind of conditions to look for.

This may be something we can do with REGEX or with some combination of string functions.

Sorry for the incomplete question Ray.

Actually the only code I have is getting the current page URL, which is below.

This is basically what I need:

if PageURL contains abc.com
        echo ('image')
elseif PageURL contains xyz.com
        echo('image2')


<?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;
					}
					?>

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I came across this.  Not sure if it's useful or not.  
<?php
						if (substr($_SERVER['REQUEST_URI'], 7, 15) == 'mydomain.com') {
    						echo 'We should see this if we are on mydomain.com';
							}
					?>

I think I have it.  

I came up with this by searching for a string inside of the URL.  If anyone sees room for improvement, please let me know!!
<?php
	$url = $_SERVER['HTTP_HOST'];//gets current page url
	if (stristr($url, 'mydomain1.com') == true)
		echo ('<a href="http://mydomain.com/">
			<img src="http://content-1.s3.amazonaws.com/images/skis/tag-cloud.jpg" alt="Save On Packages" title="Save On Packages"  width="250px"/>
		</a>');
	elseif(stristr($url, 'mydomain2.com') == true)
		echo "Womens Skis are better "; 
	elseif(stristr($url, 'mydomain3.com') == true)
		echo "SNOWBOARDS.NET"; 
?>

ID:34149644 -- that looks right to me.  In almost all instances, $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]; will give you the current, fully qualified URL, including the GET arguments.  To skip the GET arguments, change REQUEST_UTI to PHP_SELF.
