操作数组帮助函数。

Arr & ArrDots

Arr 和 ArrDots 包含一组针对数组的静态帮助方法。这些方法可以用于 array 和 \ArrayAccess 对象。有关更多信息，请参阅类内的 PHPDocs。

点操作符

Dots 是一个实现 \ArrayAccess 的实例，它使用来自 \MadeSimple\ArrDots 的函数。可以将 Dots 实例作为 array 传递给 ArrDots。

创建 Dots 有三种方式

// Create an empty dot array
$dots = new \MadeSimple\Dots();

// Create a dot array with a pre-existing array
$dots = new \MadeSimple\Dots($array);

// Create a dot array with 
$dots = new \MadeSimple\Dots([
    'address' => [
        'houseNo'  => '123',
        'street'   => 'Fake St',
        'postCode' => 'AB12 3CD',
    ],
    'comments' => [
        'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
        'Donec nec pellentesque est.',
        'Quisque volutpat quam et est laoreet, vitae consectetur erat molestie.',
    ]
]);

一旦创建 Dots，您可以按以下方式替换以下下划线数组

// Set an array after dot array
// Changes will _not_ be reflected in the original array
$dots->setArray($array);

// Set an array as a reference
// Changes will be reflected in the original array
$dots->setReference($array);

Dots 的基本用法

// Get a value using dot notation:
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Set a value using dot notation:
$dots['address.postCode'] = 'EF45 6GH';
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Remove a value using dot notation:
unset($dots['address.postCode']);
echo "Exists: ", (isset($dots['address.postCode']) ? 'yes' : 'no'), PHP_EOL;

// Add a value using dot notation:
$dots['address.postCode'] = 'IJ78 9KL';
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Access nth element in an sub array
echo "Comment: ", $dots['comments.1'], PHP_EOL;
