What is Alteryx right outer self join equal to, in pyspark?

Question

I am trying to migrate the alteryx workflow in pyspark dataframes, as part of which I came across this right outer self join on different columns (ph_id_1 and ph_id_2), while doing the same in pyspark, i am not getting the correct output, have tried Anti, left anti join. All are giving the same result. Any suggestion how to do it in pyspark way or sql way.

Tried:

df_new = df_1.join(df_2,[df_1['ph_id_1'] == df_2['ph_id_2']],how='left_anti')

, and

df_new = df_1.filter(df_1['ph_id_1'] != df_2['ph_id_2'])

Both are giving same results, different from actual one.
