What are best practices for handling MySQL queries in PHP to avoid infinite loops?

To avoid infinite loops when handling MySQL queries in PHP, it is important to properly handle errors and exceptions that may occur during the query execution. One way to prevent infinite loops is to set a timeout limit for the query execution using the `set_time_limit()` function in PHP. Additionally, using proper error handling techniques, such as try-catch blocks, can help to catch any potential errors and prevent the script from getting stuck in an infinite loop. 

// Set a timeout limit for the query execution
set_time_limit(30);

// Example of handling MySQL query with error handling
try {
    $conn = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $stmt = $conn->prepare("SELECT * FROM mytable");
    $stmt->execute();
    
    // Fetch results
    while ($row = $stmt->fetch()) {
        // Process each row
    }
} catch (PDOException $e) {
    // Handle any errors that occur during query execution
    echo "Error: " . $e->getMessage();
}
