Are there any specific PHP libraries or tools that can help with implementing secure SOAP communication over HTTPS?

To implement secure SOAP communication over HTTPS in PHP, you can use the SoapClient class with stream context options to set the necessary SSL parameters for secure communication. This includes setting the 'ssl' context option to verify the peer certificate and enable the use of HTTPS. Additionally, you can specify the SOAP endpoint URL with the 'location' option to ensure the communication is secure.

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

$options = [
    'location' => 'https://example.com/soap_endpoint',
    'uri' => 'http://example.com',
    'stream_context' => $context
];

$client = new SoapClient(null, $options);
