What is the significance of the max_allowed_packet setting in MySQL when inserting data using PHP?

The max_allowed_packet setting in MySQL determines the maximum size of a single packet or query that can be sent to the server. If this setting is too low, it can cause errors when trying to insert large amounts of data into the database using PHP. To solve this issue, you can increase the max_allowed_packet setting in your MySQL configuration file to accommodate the size of the data being inserted.

// Set max_allowed_packet setting in MySQL configuration file
$mysqli = new mysqli("localhost", "username", "password", "database");

// Increase max_allowed_packet size to 32M
$mysqli->query("SET GLOBAL max_allowed_packet=33554432");
