    ArrayObject::getArrayCopy

    (PHP 5 >= 5.0.0, PHP 7)

    ArrayObject::getArrayCopy — Creates a copy of the ArrayObject.

    Description

    public array ArrayObject::getArrayCopy ( void )

    Exports the ArrayObject to an array.

    Parameters

    This function has no parameters.

    Return Values

    Returns a copy of the array. When the ArrayObject refers to an object an array of the public properties of that object will be returned.

    Examples

    Example #1 ArrayObject::getArrayCopy() example

    <?php
    // Array of available fruits
    $fruits = array("lemons" => 1, "oranges" => 4, "bananas" => 5, "apples" => 10);

    $fruitsArrayObject = new ArrayObject($fruits);
    $fruitsArrayObject['pears'] = 4;

    // create a copy of the array
    $copy = $fruitsArrayObject->getArrayCopy();
    print_r($copy);

    ?>

    The above example will output:

    Array
(
    [lemons] => 1
    [oranges] => 4
    [bananas] => 5
    [apples] => 10
    [pears] => 4
)

    If you did something like this to make your constructor multidimensional capable you will have some trouble using getArrayCopy to get a plain array straight out of the method:
    <?php
    public function __construct( $array = array(), $flags = 2 )
    {
            // let’s give the objects the right and not the inherited name
            $class = get_class($this);

        foreach(    $array as $offset => $value)
                $this->offsetSet($offset, is_array($value) ? new $class($value) : $value);

            $this->setFlags($flags);
    }
    ?>

    That’s the way I solved it:

    <?php
    public function getArray($recursion = false)
    {
            // just in case the object might be multidimensional
            if ( $this === true)
            return     $this->getArrayCopy();

        return     array_map( function($item){
            return     is_object($item) ? $item->getArray(true) : $item;
        },     $this->getArrayCopy() );
    }
    ?>

    Hope this was useful!

    "When the ArrayObject refers to an object an array of the public properties of that object will be returned."

    This description does not seem to be right:

    <?php
    class A
    {
        public     $var = 'var';
        protected     $foo = 'foo';
        private     $bar = 'bar';
    }

    $o = new ArrayObject(new A());
    var_dump($o->getArrayCopy());

    /*
    Dumps:

    array(3) {
      ["var"]=>
      string(3) "var"
      ["*foo"]=>
      string(3) "foo"
      ["Abar"]=>
      string(3) "bar"
    }
    */
    ?>

    So it does not only include the public properties.
