What is the difference between using $_POST and $_GET to access variables in PHP when passing them between frames?

When passing variables between frames in PHP, using $_POST is more secure as it sends data through the HTTP request body rather than the URL, making it less visible to users. On the other hand, using $_GET passes variables through the URL, making them visible to users and potentially exposing sensitive information. Therefore, it is recommended to use $_POST when passing variables between frames for better security. 

// Frame 1 (sending data)
<form action="frame2.php" method="post">
    <input type="hidden" name="variable_name" value="value_to_pass">
    <input type="submit" value="Submit">
</form>
```

```php
// Frame 2 (receiving data)
<?php
if(isset($_POST['variable_name'])){
    $received_variable = $_POST['variable_name'];
    echo $received_variable;
}
?>
