php true方法使用mysqli连接到处[关闭]

Question

I have a MySQLi connection object to connect to mysql as this :

require_once('config.php');


//new mysqli object
$mysqli = new mysqli(MYSQL_HOSTNAME, MYSQL_USERNAME, MYSQL_PASSWORD, MYSQL_DATABASE);

/* check connection */
if ($mysqli->connect_errno) {
    printf("Connect failed: %s
", $mysqli->connect_error);
    exit();
}

and I've included this file into any files to have connection

Is it right way? I think in my every files , I will have new connection to MySQL.

Answer 1

Php does not have control over how many connections you will have. Mysql manages the pool internally and will allocate connections according to the max_connections parameter for example (not sure of exact parameter name).

Creating 10 connection objects does not mean having 10 opened connections.
