PHP IF - ELSE codes based on URL

Can some one help me out in this?

I want to know the codes for a Php if, else condition tags based on URL.

I want it like,

if url=domain.com
echo <div> dont show domain button<div>

else

echo <div> dont do nothing </div>


and


if url=something.domain.com
echo <div> dont show something button <div>

else

echo <div> do nothing </div>


I hope you got the thing from the Framework

i.e When running on the domain url, i dont want to see domain link on the page in the nav bar i make.
and when am in the subdomain, i dont want to see that subdomian link in nav bar. I can arrange the things for navbar. but not so sure about the PHP code.

Can some one help me out and clear this giving me the code?

also i would like a wildcard it the cases like if it is domain.com/* so it remain correct for all the pages in the blog

 

<?php

$url = str_replace("www.", "", $_SERVER['HTTP_HOST']);

if ($url == "domain.com") {
echo "<div>dont show domain button</div>";

} else {

echo "<div>dont do nothing</div>";

}



if ($url == "something.domain.com") {
echo "<div>dont show something button</div>";

} else {

echo "<div>do nothing</div>";

}

?>

Thanks For the Time spent for framing the code. Actually i tried using it, But Only the First If and Else Gets Exceuted and result shows. I.e Subdomain has no changes visible Why is that?

 

Try this

<?php

$url = str_replace("www.", "", $_SERVER['HTTP_HOST']);


switch ($url)
case 'domain.com':
{
echo "<div>dont show domain button</div>";
break;
case 'something.domain.com':
echo "<div>dont show domain button</div>";
break;
default:
echo "<div>dont do nothing</div>";
break;
}

And say the Results
