Just in case:



'max_allowed_package' is a MySQL variable; it is not a PHP function/variable/constant.

send_long_data() these function is normaly used to store Data in Binary blob field. But if the table is UTF8 and connection charset it does not expect binary data (for example images) it take utf8 Data.

This mean you have to do utf8_encode bevore sending binary data.
