Answer 1

PDO's default buffer size is 1 MB (1048576), try bumping it up to 2 MB (2097152)

If you are using PDO directly, pass this as the 4th argument

$pdo = new PDO(
    $dsn,
    $username,
    $password,
    array(PDO::MYSQL_ATTR_MAX_BUFFER_SIZE => 2097152)
);

If you are using Laravel, this can be done via the config/database.php file by adding an array of options to your connection

// ...
    'mysql' => array(
        'driver'    => 'mysql',
        // ...
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'options'   => array(
            PDO::MYSQL_ATTR_MAX_BUFFER_SIZE => 2097152
        ),
    ),
// ...
