Here is th

Answer 1

This is not related to the original question, but i had the same error-message and this thread is the first hit in Google and it took me a while to figure out what the Problem was, so it May be of use for others:

i'm NOT using mysqli, still using mysql_connect i had some simple querys, but ONE query caused all other querys to fail within the same Connection.

I use mysql 5.7 and php 5.6 i had a table with the data-Type "JSON". obviously, my php-version did not recognize the return value from mysql (php just did not know what to do with the JSON-Format because the built-in mysql-module was too old (at least i think))

for now i changed the JSON-Field-Type to Text (as for now i don't need the native mysql JSON-functionality) and everything works fine
