What are the best practices for handling MySQL resources and fetching data in PHP to avoid issues like the one described in the thread?

Issue: The issue described in the thread is likely related to not properly closing MySQL connections after fetching data, which can lead to resource exhaustion and performance issues. To avoid this problem, it is essential to always close database connections and free up resources when they are no longer needed. Best practice code snippet for handling MySQL resources in PHP: 

// Establish a connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Fetch data from the database
$result = $mysqli->query("SELECT * FROM table");

// Process the fetched data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Do something with the data
    }
} else {
    echo "No results found";
}

// Free up resources and close the connection
$result->free();
$mysqli->close();
