Undefined property: $DocumentCollections

[keepscoding]

$host = "https://docdb-sample.documents.azure.com:443/"; //retrieved from URI
$master_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx='; //retrieved from PRIMARY KEY

I follow your sample code to call and i got below error.
Do i need install any lib?
