### toArray()

[](#toarray)

You can get an array representation of the current structure with the `toArray()` method.

```
$array = Construct::linkedList()
    ->add(4)
    ->toArray();
```

### dump() 🚽 & dumpAndDie() ☠

[](#dump---dumpanddie-)

Constructs uses the var\_dumper Symfony component. You can use the `dump()` method on your structures.

```
$list = Construct::linkedList()
    ->add(4)
    ->dump()
    ->remove(4)
    ->dump();
```

If you are more a "Dump and die" person, `dumpAndDie()` method is also available.

```
$list = Construct::linkedList()
    ->add(4)
    ->add(2)
    ->remove(4)
    ->add(6)
    ->dumpAndDie();
```
