Are there any recommended tutorials for learning about SOAP in PHP, especially focusing on German-language resources?

There are several tutorials available online for learning about SOAP in PHP, but finding resources specifically in German may be more challenging. One recommendation is to search for German-language PHP forums or websites that offer tutorials on SOAP integration. Additionally, translating English tutorials using tools like Google Translate can also be helpful in understanding the concepts. Unfortunately, I cannot provide a specific PHP code snippet for this issue as it involves finding German-language resources for learning about SOAP in PHP.
