Are there specific tutorials or resources available for beginners in PHP web development to address common issues like data validation?

Data validation is crucial in PHP web development to ensure that the data inputted by users is accurate and secure. Common issues include validating user input such as email addresses, passwords, and form submissions. To address this, developers can use built-in PHP functions like filter_var() and regular expressions to validate and sanitize user input before processing it further. Example PHP code snippet for validating an email address: 

$email = $_POST['email'];

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    // Invalid email address
    echo "Invalid email address";
} else {
    // Valid email address
    echo "Email address is valid";
}
