+
+The `Arr::from` method converts various input types into a plain PHP array. It supports a range of input types, including arrays, objects, and several common Laravel interfaces, such as `Arrayable`, `Enumerable`, `Jsonable`, and `JsonSerializable`. Additionally, it handles `Traversable` and `WeakMap` instances:
+
+```php
+use Illuminate\Support\Arr;
+
+Arr::from((object) ['foo' => 'bar']); // ['foo' => 'bar']
+
+class TestJsonableObject implements Jsonable 
+{
+    public function toJson($options = 0) 
+    {
+        return json_encode(['foo' => 'bar']);
+    }
+}
+
+Arr::from(new TestJsonableObject); // ['foo' => 'bar']
+```
