Mark pure mysqli_ result-metadata functions as hasSideEffects=false 
Functions like mysqli_fetch_fields, mysqli_fetch_field_direct,
mysqli_num_rows, and mysqli_num_fields always return the same value
for the same mysqli_result — they read fixed metadata and don't
advance any cursor. These should not be marked as having side effects.
