What are best practices for handling multiple simultaneous queries in mysqli prepared statements in PHP?

When using mysqli prepared statements in PHP, it is important to handle multiple simultaneous queries properly to avoid conflicts. One way to do this is by using separate mysqli objects for each query to ensure they do not interfere with each other. Additionally, you can use transactions to group multiple queries together and ensure they are executed atomically. 

// Create separate mysqli objects for each query
$mysqli1 = new mysqli($host, $user, $password, $database);
$mysqli2 = new mysqli($host, $user, $password, $database);

// Begin a transaction
$mysqli1->begin_transaction();

// Execute query 1
$stmt1 = $mysqli1->prepare("INSERT INTO table1 (column1) VALUES (?)");
$stmt1->bind_param("s", $value1);
$stmt1->execute();

// Execute query 2
$stmt2 = $mysqli2->prepare("INSERT INTO table2 (column2) VALUES (?)");
$stmt2->bind_param("s", $value2);
$stmt2->execute();

// Commit the transaction
$mysqli1->commit();

// Close the mysqli objects
$mysqli1->close();
$mysqli2->close();
