Update HttpTransport.php

[giko45]

using a format on the builder gave an error.

    -> format(Format::JSON_COMPACT)

The sql send to clickhpuse server contained 2 FORMAT settings.

Have you tested this? I think this can lead to an exception because of calling json_decode on request result.

[giko45]

Yes i tested my use case (i did not run the included tests). It required an change in the builder too. See:
the-tinderbox/ClickhouseBuilder#28

However by writing a raw select i can use the Clickhouse JSONCompact format without modifications to ClickhouseClient and/or Builder
-> select("select * from table order by time DESC limit 5000 FORMAT JSONCompact")

[giko45]

Sorry,

even writing a raw select like this
-> select("select * from table order by time DESC limit 5000 FORMAT JSONCompact")
needs the modification in this PR to work.

json_decode on request result works without issues. JSONCompact is still valid json
