How can PHP beginners effectively learn the basics of form handling and variable manipulation?

PHP beginners can effectively learn the basics of form handling and variable manipulation by practicing with simple examples and tutorials. They can start by creating a basic HTML form and using PHP to handle the form submission, retrieve the form data using $_POST or $_GET, and manipulate variables to perform calculations or display information. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve form data
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Display form data
    echo "Name: " . $name . "<br>";
    echo "Email: " . $email;
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <label for="name">Name:</label>
    <input type="text" name="name" id="name"><br>
    
    <label for="email">Email:</label>
    <input type="email" name="email" id="email"><br>
    
    <input type="submit" value="Submit">
</form>
