How can the "packet is bigger than allowed_packet_size" error be avoided when inserting multiple records into a MySQL database using PHP?

When inserting multiple records into a MySQL database using PHP, the "packet is bigger than allowed_packet_size" error can occur if the data being inserted exceeds the maximum packet size allowed by MySQL. To avoid this error, you can increase the value of the `max_allowed_packet` variable in your MySQL configuration file. Alternatively, you can break up the data into smaller chunks before inserting it into the database. 

// Increase the max_allowed_packet size in your MySQL configuration file
// OR break up the data into smaller chunks before inserting

// Example of breaking up data into smaller chunks
$records = // array of records to be inserted

$chunkSize = 100; // number of records per chunk
$chunks = array_chunk($records, $chunkSize);

foreach ($chunks as $chunk) {
    $values = [];
    foreach ($chunk as $record) {
        $values[] = "('".$record['column1']."', '".$record['column2']."')";
    }
    
    $query = "INSERT INTO table_name (column1, column2) VALUES " . implode(", ", $values);
    
    // Execute the query
    // mysqli_query($connection, $query);
}
