Yet another array path implementation

Requirements

• PHP 7.1+

Usage

get()

echo (new \PeeHaa\ArrayPath\ArrayPath())->get(['foo' => ['bar' => 'baz']], 'foo.bar'); // baz
    
echo (new \PeeHaa\ArrayPath\ArrayPath())->get(['foo' => ['bar' => 'baz']], 'foo.qux'); // throws \PeeHaa\ArrayPath\NotFoundException

exists()

echo (new \PeeHaa\ArrayPath\ArrayPath())->exists(['foo' => ['bar' => 'baz']], 'foo.bar'); // true
    
echo (new \PeeHaa\ArrayPath\ArrayPath())->exists(['foo' => ['bar' => 'baz']], 'foo.qux'); // false

set()

$array = [];

(new \PeeHaa\ArrayPath\ArrayPath())->set($array, 'foo.bar', 'value');
    
var_dump($array);

/**
array(1) {
  ["foo"]=>
  array(1) {
    ["bar"]=>
    string(5) "value"
  }
}
*/

remove()

    $array = ['foo' => ['bar' => 'value']];

    (new \PeeHaa\ArrayPath\ArrayPath())->remove($array, 'foo.bar');
    
    var_dump($array);

/**
array(1) {
  ["foo"]=>
  array(0) {
  }
}
*/

Note: remove() will not throw when the key does not exist in the array.
