What is the difference between passing parameters via POST and GET in PHP?
When passing parameters via POST in PHP, the data is sent through the HTTP request body, making it more secure as the parameters are not visible in the URL. On the other hand, when passing parameters via GET, the data is sent through the URL, which can be seen by users and stored in browser history, making it less secure.
// Using POST method to pass parameters
<form action="process.php" method="post">
<input type="text" name="username">
<input type="password" name="password">
<button type="submit">Submit</button>
</form>
```
```php
// Using GET method to pass parameters
<form action="process.php" method="get">
<input type="text" name="username">
<input type="password" name="password">
<button type="submit">Submit</button>
</form>
