How can PHP developers troubleshoot SSL issues and ensure that data is securely transmitted over HTTPS?

To troubleshoot SSL issues and ensure secure data transmission over HTTPS, PHP developers can check for SSL certificate validity, verify the server's SSL configuration, and confirm that the data is being transmitted securely. They can also use PHP functions like stream_context_create() to set SSL options and verify the SSL certificate. 

$context = stream_context_create([
    'ssl' => [
        'verify_peer' => true,
        'verify_peer_name' => true,
        'allow_self_signed' => false
    ]
]);

$response = file_get_contents('https://example.com', false, $context);

if ($response === false) {
    echo "Error fetching data over HTTPS.";
} else {
    echo "Data securely transmitted over HTTPS.";
}
