Are there potential performance issues when using multiple update queries in PHP on a localhost server?

When using multiple update queries in PHP on a localhost server, there can be potential performance issues due to the overhead of establishing a new connection for each query. To solve this problem, you can use a single database connection for all the update queries by reusing the connection object. 

// Create a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Perform multiple update queries using the same connection
$sql1 = "UPDATE table1 SET column1 = 'value1' WHERE id = 1";
$sql2 = "UPDATE table2 SET column2 = 'value2' WHERE id = 2";

if ($conn->query($sql1) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

if ($conn->query($sql2) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

// Close the connection
$conn->close();
