What are the differences between using require and include in PHP scripts?
The main difference between require and include in PHP scripts is how they handle errors. When using require, if the file being included is not found, it will produce a fatal error and halt the script execution. On the other hand, include will only produce a warning and allow the script to continue running. It is generally recommended to use require when including essential files that are crucial for the script to function properly.
// Using require to include a file
require 'myfile.php';
```
```php
// Using include to include a file
include 'myfile.php';
