SSL Switcher

PHP class to enforce an SSL connection in a website.

Installation

Simply require the package in your composer.json file.

composer require "mistralys/ssl-switcher"

Quick start

The simplest way to use the script is to use the static autoSwitch() method:

use Mistralys\SSLSwitcher;

SSLSwitcher::autoSwitch('https://domain.extension');

This will check if the current connection is SSL or not, and redirect to the target URL as needed. Otherwise, the script continues as usual.

NOTE: Any existing request parameters are appended to the target URL, to stay on the same page.

SSL switching conditions

The script will redirect to the https version of the website only if the following conditions are met:

1. The script is not run from the command line
2. The script is not running from localhost
3. SSL is not enabled

Using class methods

When instantiating the class, you get access to its methods - for example to run some checks in your application before doing the switch to https.

use Mistralys\SSLSwitcher;

$switcher = new SSLSwitcher('https://domain.extension');

// Is a switch to https required?
if($switcher->isSwitchRequired())
{
    // Do something before the redirect
}

// Redirect
$switcher->switch();

Utility methods

The class has a few utility methods that can come in handy.

• isCLI() - Is the script running from the command line?
• isLocalhost() - Is the server run as localhost / 127.0.0.1?
• isSSLActive() - Is SSL enabled?
• getTargetURL() - The URL the script would redirect to.

Disabling the exit call

By default, the class will call exit() after the redirect. If your application needs to handle this instead, the exit can be turned off:

use Mistralys\SSLSwitcher;

$switcher = new SSLSwitcher('https://domain.extension');
$switcher->setExitEnabled(false);
$switcher->switch();

// Handle the exit in the script instead
if($switcher->isSwitchRequired())
{
    exit();
}
