$arrayReader = new ArrayReader(
    array(
        'hash' => array(
            'with' => array(
                'nested' => 'value'
            )
        )
    )
);

echo $arrayReader->stringValue('hash.with.nested'));

//Output: value

$arrayReader = new ArrayReader(
    array(
        'hash' => array(
            'with' => array(
                'nested' => 'value'
            )
        )
    )
);

echo $arrayReader->stringValue('hash.not.existing.path', 'defaultString'));

//Output: defaultString


//If a key in your array contains a dot you escape it in the path with a backslash

$arrayReader = new ArrayReader(
    array(
        'hash' => array(
            'with.dot.key' => array(
                'nested' => 'value'
            )
        )
    )
);

echo $arrayReader->stringValue('hash.with\.dot\.key.nested'));

//Output: value

//If you need to differentiate between a NULL value and a not existing path, you can explicity check if the path exists:

$arrayReader = new ArrayReader(
    array(
        'hash' => array(
            'with' => array(
                'nested' => null
            )
        )
    )
);

if($arrayReader->pathExists('hash.with.nested')) {
    echo "path exists";
}

//Output: path exists
