How can HTML forms be used as an alternative to JavaScript for certain functionalities in PHP?

HTML forms can be used as an alternative to JavaScript for certain functionalities in PHP by utilizing form submissions to trigger PHP scripts. This can be achieved by setting the form's action attribute to the PHP script that needs to be executed and using input elements to pass data to the script. PHP can then process the form data and perform the necessary actions based on the input received. 

```php
<form action="process_form.php" method="post">
    <input type="text" name="username" placeholder="Enter username">
    <input type="password" name="password" placeholder="Enter password">
    <input type="submit" value="Submit">
</form>
```

In the above example, when the form is submitted, the data entered in the input fields will be sent to the "process_form.php" script using the POST method. The PHP script can then access the submitted data using the $_POST superglobal and perform any necessary actions based on the input received.
