如何使用我的 URL 中的 GET[] 解决这个 PHP 问题

Question

if (isset($_GET['debug'])) {
    if(boolval($_GET['debug']) ? true : false)
    {
        echo "Using Distribution Certificate";
        stream_context_set_option($ctx, 'ssl', 'local_cert','cert.pem');
        $fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
    } else {
        echo "Using Development Certificate";
        stream_context_set_option($ctx, 'ssl', 'local_cert','certdevelopment.pem');
        $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
    }
}else{
    // Fallback behaviour goes here
    echo "Fallback Call To Use Distribution Certificate";
    stream_context_set_option($ctx, 'ssl', 'local_cert','cert.pem');
    $fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
}

When my URL is https://localhost/index.php?debug=true

I want to use the Distribution Certificate. If it's false then use the Development Certificate.

If anything else is there then we use the Distribution certificate.

Unfortunately when my PHP script executes, it is always using the "Distribution Certificate". even when I set it to false. I think the "boolval" method is not working all the time.

Instead of

if(boolval($_GET['debug']) ? true : false)

You should compare the values using

if($_GET['debug'] == 'true')

This is because both "true" and "false" evaluate to true when cast to a boolean. Check the test cases in the manual for more examples.
