php - Check if MySQL server is running before retriving data from it -


what correct way of checking if mysql server , running before trying retrieving data ?

i'm using php , mysqli in object orientated way.

i'm semi-new mysqli , managed write useful website. voting system.

i have code on website retrieves data mysql server , displays on website.

this works fine long @ mysql server , running , able connect it.

but if turn off mysql server or otherwise php code not able connect sql server website hangs while until timeout , part of website not displayed.

according mysqli documentation,

if ($mysqli->connect_errno) {     echo "failed connect mysql: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error; }

i further suppose check value of connect_errno better idea of why connection failed.
