How to correctly form a SOAP request in PHP?

Question

PHP

Good day everyone. I am addressing here with a question, maybe they will help here)
In general, the essence is this. We carry out integration with XML SOAP interfaces of various tour operators
I myself am weak in SOAP. I've done integration with 2 operators up to now.
By trial and error, something worked out
. But with Pegasus, somehow everything doesn't work out ( In general, you can help with the formation of an
XML request for a SOAP service at
the end)
Can you provide PHP code that performs this task?
Thanks everyone in advance for help

PHP has a library for working with SOAP. The principle of its operation is described, for example, here .
