SoapUI WSDL call to PHP (curl or SoapClient)

Hi insurteched​ 

The issue you're facing sounds from PHP's native SoapClient lacking native support for generating WS-Security UsernameToken headers with PasswordDigest, Nonce, and Timestamp, which is a format SoapUI can produce when configured accordingly.

• Seems your PHP code fails to generate the required WS-Security header format, leading to the [ns1:InvalidSecurity] error.
• This discrepancy arises because SoapUI can automatically generate WS-Security headers when configured, whereas PHP SoapClient only supports basic HTTP authentication and lacks built-in support for WS-Security UsernameToken with PasswordDigest.

Consider using a PHP library that supports WS-Security, such as robrichards/wse-php, which can help generate the required WS-Security headers.

Use a library such as robrichards/wse-php to generate the correct WS-Security headers in PHP. This will allow your PHP server-side code to authenticate successfully with services that require UsernameToken with PasswordDigest, Nonce, and Timestamp—matching what SoapUI produces78.

Thank you very much and have a great one!
