PHP - check if SSL is enabled

ssl.php

<?php
function is_ssl() {
	if ( isset($_SERVER['HTTPS']) ) {
		if ( 'on' == strtolower($_SERVER['HTTPS']) )
		return true;
		if ( '1' == $_SERVER['HTTPS'] )
		return true;
	} elseif ( isset($_SERVER['SERVER_PORT']) && ( '443' == $_SERVER['SERVER_PORT'] ) ) {
		return true;
	}
		return false;
	}
?>

Thanks Jubalm.

Why you check 443. Why we check this case?

HTTPS connections utilize the TCP port 443 as a standard

Thanks.

Hi and thanks for the script - good work.

I look after an option so I can send output from the script to the browser. I think about the following:

1. If SSL is not activated when the webpage is loaded the script should write "Your connection is not sure"
2. If SSL is activated when the webpage is loaded the script should write "Your connection is sure".

I will be glad if someone here please can give me the trick regarding what I should add to the script.

Thanks in advance for your answer, and have a nice day.

Regards,
Anders
