Redirecting HTTP to HTTPS with PHP

Today i am showing you how to redirect http to https or force users to redirect with HTTPS instead of HTTP using php with non www url to www url.

Over the past few years, HTTPS has risen in popularity – especially since Google announced that HTTPS was being used as a ranking signal for websites.

<?php
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on")
{
	$pageURL .= "s";
}
$pageURL .= "://";
$url1 = $_SERVER["SERVER_NAME"];
$params = explode('.', $url1);
if($pageURL!="https://")
{
	if(sizeof($params === 3) AND $params[0] == 'www')
	{
		$pageURL ="https://". $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
		header("Location: ".$pageURL);
	}
	else
	{
		$pageURL ="https://www.". $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
		header("Location: ".$pageURL);
	}
}
else
{
	if(sizeof($params === 3) AND $params[0] == 'www')
	{
	}
	else{
		$pageURL ="https://www.". $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
		header("Location: ".$pageURL);
	}
}
?>

The code above is pretty simple. It checks the HTTPS variable in the $_SERVER super global array to see if it equal to “on”. If the variable is not equal to “on”, then agian checking whether URl is with “www” or without “www” then it redirects the user to the HTTPS version with “www” of the current URL. If URL already with https then we check whether URl is with “www” or without “www” and redirect with https and “www”.
