PHP Keeping a PDO ATTR_PERSISTENT connection alive

Question

I am running an endless PHP Script with PDO Persistent Connection like this:

$conn=new PDO(
  \'mysql:host=127.0.0.1\',\'user\',\'pass\', array(PDO::ATTR_PER

I would suggest you another way to handle such situations. Whenever you need to run a query in your long-lasting script ensure that there is a connnection. Otherwise reconnect.

    try {
        echo "Testing connection...\n";
        $old_errlevel = error_reporting(0);
        self::$pdo->query("SELECT 1");
    } catch (PDOException $e) {
        echo "Connection failed, reinitializing...\n";
        self::init();
    }

You can find the full class example here. I also suggest you to explicitly close the connection in your script when you know you will not use it for a long period.
