php-mysqlHow to keep a connection open in PHP and MySQL?

To keep a connection open in PHP and MySQL, you can use the mysqli_connect() function. This function takes in the database host, username, password, and database name as parameters and returns a connection object.

$conn = mysqli_connect("localhost", "username", "password", "database_name");

The code above will create a connection object $conn which can be used to execute queries on the database. To keep the connection open, you can use the mysqli_ping() function. This function takes in the connection object as a parameter and returns true if the connection is still alive.

if (mysqli_ping($conn)) {
    echo "Connection is still alive";
}

The code above will check if the connection is still alive and print out a message if it is.

Parts of the code:

• mysqli_connect(): This function takes in the database host, username, password, and database name as parameters and returns a connection object.
• mysqli_ping(): This function takes in the connection object as a parameter and returns true if the connection is still alive.
• if statement: This statement checks if the connection is still alive and prints out a message if it is.
