How does the use of $_GET[] parameters in PHP compare to other methods of passing data between pages?

When using $_GET[] parameters in PHP, data is passed through the URL, making it visible to users and potentially less secure. Other methods of passing data between pages, such as using $_POST[] or sessions, are more secure as they do not expose data in the URL. It is important to consider the sensitivity of the data being passed and choose the appropriate method accordingly. 

// Example of passing data using $_POST[] instead of $_GET[] for increased security
<form method="post" action="page2.php">
    <input type="text" name="data">
    <input type="submit" value="Submit">
</form>

// page2.php
<?php
$data = $_POST['data'];
echo "Data received: " . $data;
?>
