Catch“Warning：mysqli :: mysqli（）[mysqli.mysqli]：MySQL server has gone away”很好地写入错误

Question

在哪里以及如何编写代码来检查显示“MySQL服务器已经消失”的错误并且打印出不同的更好的错误。

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

Answer 1

还有另一个帖子里回答了这个（Solving "MySQL server has gone away" errors）用下面的代码片段：

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; 
    } 
}
