How can beginners effectively use $_POST and $_GET variables to pass data between PHP pages?

To pass data between PHP pages using $_POST and $_GET variables, beginners can use forms to send data via POST method and URL parameters to send data via GET method. By accessing the $_POST and $_GET superglobals in the receiving PHP page, the data can be retrieved and processed accordingly. 

// Sending data using POST method
<form method="post" action="page2.php">
    <input type="text" name="data">
    <button type="submit">Submit</button>
</form>

// Receiving data using POST method in page2.php
<?php
if(isset($_POST['data'])){
    $data = $_POST['data'];
    // Process the data
}
?>

// Sending data using GET method
<a href="page2.php?data=value">Link</a>

// Receiving data using GET method in page2.php
<?php
if(isset($_GET['data'])){
    $data = $_GET['data'];
    // Process the data
}
?>
