Cast / convert a stdClass (or any other class) to another class
===============================================================

[![Minimum PHP version: 7.4.0](https://camo.githubusercontent.com/89e54687773afb25f5943cfbd66376d73e2ce50874c54429a78aac45cb6bcf84/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f7068702d372e342e302532422d626c75652e737667)](https://camo.githubusercontent.com/89e54687773afb25f5943cfbd66376d73e2ce50874c54429a78aac45cb6bcf84/68747470733a2f2f696d672e736869656c64732e696f2f62616467652f7068702d372e342e302532422d626c75652e737667)

ABOUT
-----

[](#about)

Allows you to cast a stdClass (or any other class) to some other class.

INSTALL
-------

[](#install)

```
composer require rfx/cast
```

USAGE
-----

[](#usage)

### Problem

[](#problem)

So you received a beautiful object that you want to use

```
stdClass Object
(
    [name] => home
    [at] => stdClass Object
        (
            [x] => 4
            [y] => 5
        )
)

```

However:

- Your IDE hates it
- All static analysis tools hate it
- No autocompletion
- No type checks

### Solution

[](#solution)

```
declare(strict_types=1);
// Create class(es) that define(s) those properties
use rfx\Type\Cast;
class Point {
    public int $x;
    public int $y;
}

class Location {
    public string $name;
    public Point $at;
}

function getLocation(): Location {
    // Get your object (from a json source, some external lib, ...).
    // As demonstration we create one here from an array.
    $obj = (object)['name' => 'home', 'at' => ['x' => 4, 'y' => 5]];
    // Cast it (this works recursively, e.g. Location contains a Point object)
    return Cast::as($obj, Location::class);
}

$l = getLocation();
```

### Result

[](#result)

```
Location Object
(
    [name] => home
    [at] => Point Object
        (
            [x] => 4
            [y] => 5
        )
)

```

- Your IDE loves you again
- All static analysis tools will help you find problems
- Autocompletion, type checks, etc. work again

### Speed

[](#speed)

If performance is important and:

- you are casting many objects of the same type
- all your objects are shallow (no nesting)
- all the properties are scalar types

then you can use the faster alternative, which is as performant as a normal constructor:

```
declare(strict_types=1);
// Create a proper class that defines those properties
use rfx\Type\Cast;
class Point {
    public string $name;
    public int $x;
    public int $y;
}

/** @return Point[] */
function getPoints(): array {
    // Get your objects (from a json source, some external lib, ...).
    // As demonstration we create a million from an array.
    $obj = (object)['name' => 'P1', 'x' => 4, 'y' => 5];
    $objs = array_fill(0, 1000000, $obj);
    // Create a factory
    $cf = new Cast(Point::class);
    // Cast them all
    return array_map([$cf, 'cast'], $objs);
}

$p = getPoints();
```

LIMITATIONS
-----------

This section needs to be written, and some future plans added.
