What are some best practices for passing a variable number of variables to a method in PHP?

When passing a variable number of variables to a method in PHP, one common approach is to use the `func_get_args()` function to retrieve all passed arguments as an array. Another approach is to use the `...$args` syntax in the method signature to accept a variable number of arguments as an array. This allows for flexibility in the number of arguments passed to the method.

// Using func_get_args() to retrieve all passed arguments
function exampleMethod() {
    $args = func_get_args();
    
    foreach ($args as $arg) {
        echo $arg . ' ';
    }
}

exampleMethod('Hello', 'World', '!');
```

```php
// Using ...$args syntax to accept a variable number of arguments
function exampleMethod(...$args) {
    foreach ($args as $arg) {
        echo $arg . ' ';
    }
}

exampleMethod('Hello', 'World', '!');
