What are the differences between executing PHP code in a browser versus in the command line?

When executing PHP code in a browser, the output is displayed directly on the webpage, while executing PHP code in the command line will display the output directly in the terminal window. Additionally, PHP code executed in the command line can be useful for running scripts or tasks without the need for a web server. To execute PHP code in the command line, you can use the `php` command followed by the path to the PHP file. 

<?php
echo "Hello, World!";
```

To execute the above PHP code in the command line, save it in a file (e.g., `hello.php`) and run the following command in the terminal:

```
php hello.php
