What are the common mistakes or misconceptions beginners make when passing variables between PHP pages using links or forms?

One common mistake beginners make when passing variables between PHP pages using links or forms is not properly using either GET or POST methods. To pass variables through links, you should use GET method by appending the variables to the URL. To pass variables through forms, you should use POST method by setting the form method attribute to "post". 

// Passing variables through links using GET method
<a href="page2.php?variable=value">Link</a>

// Retrieving the variable on page2.php
$variable = $_GET['variable'];
```

```php
// Passing variables through forms using POST method
<form action="page2.php" method="post">
    <input type="hidden" name="variable" value="value">
    <button type="submit">Submit</button>
</form>

// Retrieving the variable on page2.php
$variable = $_POST['variable'];
