FYI it's 2021 not 1995. Nobody serious uses PHP, JVM is the dominant server application platform and Python is used extensively across a range of backend scenarios with a particular popularity in the areas
of data & analytics (pandas, scipy, pyspark etc), scheduling & orchestration (airflow et al) and configuration management (ansible).
