Is it advisable to learn SQL independently from a specific programming language and database system before diving into PHP and MySQL books?

It is advisable to learn SQL independently before diving into PHP and MySQL books as SQL is the language used to interact with databases, including MySQL. Understanding SQL fundamentals will give you a solid foundation for working with databases in PHP. Once you are comfortable with SQL, you can then move on to learning how to integrate PHP with MySQL for dynamic web development. 

// Example PHP code snippet connecting to a MySQL database using SQL
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

echo "Connected successfully";

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