XML Request: Sensor Observation

[hinay]

Hallo Team,

ich will mit PHP einen XML request mit einer GetObservation durchführen. Mit Python kann ich den request bereits durchführen, aber mit PHP kann ich es nicht umsetzen. Die Messwerte (Temperatur) sollen anschließend in einem Array gespeichert werden. Hat jemand bereits einen request mit PHP gestellt und kann mir weiter helfen?

Hier der Python Request:
requestXml = """
