出现在何处以及如何编写代码，以检查显示“ MySQL服务器已消失”的错误，并更好地打印出一些错误。

Warning: mysqli::mysqli() [mysqli.mysqli]: MySQL server has gone away

Answer 1

There is another post that answers this ( Solving "MySQL server has gone away" errors ) with the following code snippet:

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;
  }
}
