struct

struct-like trait for PHP., _(*1)

Usage

Create a struct by using the struct trait in a class and declaring public properties. You can then read and write those properties using the arrow (->) operator. Any attempt to access an undefined, protected, or private property will result in an exception.
You can also use the constructor to set all properties at once., _(*2)

Example:, _(*3)

<?php

use lpeltier\Struct;

class Foo
{
    use Struct;

    public $foo = 'default';
    public $bar;
}

$foo = new Foo(['bar' => 0x2A]);

var_dump($foo->foo); // 'default'
var_dump($foo->bar); // 42
var_dump($foo->baz); // throws an exception

Why

PHP automatically creates unknown properties when you set them, without even throwing a notice. This can lead to one those silly bugs that takes ages to find because you wrote 'nuw' instead of 'num'., _(*4)
