question:

Error while sending query packet in PHP runtime

reason:

Run show variables like ‘max in MySQL_ allowed_ packet’;

View Max_ allowed_ Packet value, if Max_ allowed_ If the packet value is too low, the title error will be reported

solution:

Edit my.cnf (my.ini under Windows) and modify it in the [mysqld] section or the server configuration section of MySQL_ allowed_ Packet = 50m (or max_ allowed_ packet = 50 * 1024 * 1024）

command line modify set global Max_ allowed_ packet = 50 * 1024 * 1024
