Requesting SOAP using CURL on Codieigniter 4

You will need to provide us with code on how you use the SoapClient and what error you get. I guess you mean the official one?
https://www.php.net/manual/en/class.soapclient.php

Most likely you need to put \ in front of every function.

From:
SoapClient

Into:
\SoapClient

Thank you so much. That work :-) Really Appreciate it jreklund
