What common errors can occur when using MySQL functions in PHP scripts?

One common error when using MySQL functions in PHP scripts is not properly handling errors or exceptions that may occur during database operations. To solve this issue, it is recommended to use try-catch blocks to catch and handle any potential errors that may arise. 

try {
    // Connect to the database
    $conn = new mysqli($servername, $username, $password, $dbname);
    
    // Check for connection errors
    if ($conn->connect_error) {
        throw new Exception("Connection failed: " . $conn->connect_error);
    }
    
    // Perform database operations here
    
} catch (Exception $e) {
    // Handle any errors that occur during database operations
    echo "Error: " . $e->getMessage();
}
