Answer 1

还有另一篇文章使用以下代码段解答此问题（Solving "MySQL server has gone away" errors）：

try {
  $conn = getDbConn();
  saveData($conn, $val);
} catch (DbException $e) {
  if (strstr($e->getMessage(), 'MySQL server has gone away') {
    // WRITE OUT NICE LOG HERE AND RETRY IF WANTED
    ....
    // RETRY
    $conn = getDbConn();
    saveData($conn, $val);
  } else {
    // we have a problem connecting or something, pass the exception along
    throw $e;
  }
}
