How Can I Enforce SSL/HTTPS for Specific PHP Pages Using .htaccess and mod_rewrite?

Enforcing SSL/HTTPS with .htaccess and mod_rewrite for Specified PHP Pages

To enforce SSL/HTTPS for specific PHP pages using .htaccess and mod_rewrite, consider the following approaches:

1. mod_ssl: Utilize the SSLRequireSSL Directive within the Apache configuration to restrict access unless HTTPS is enabled for the connection. However, this method does not provide redirects.
2. mod_rewrite: Configure mod_rewrite in your .htaccess file to redirect non-HTTPS requests to the HTTPS version:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

3. PHP-based Enforcement: In case .htaccess access is restricted, you can implement enforcement within your PHP code:

if (!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] !== 'on') {
    if(!headers_sent()) {
        header("Status: 301 Moved Permanently");
        header(sprintf(
            'Location: https://%s%s',
            $_SERVER['HTTP_HOST'],
            $_SERVER['REQUEST_URI']
        ));
        exit();
    }
}

By utilizing these techniques, you can effectively redirect specific PHP pages to their HTTPS versions and enforce SSL/HTTPS for enhanced security.
