view querying needs to be more straightforward; e.g. character strings of decimal digits are serialised over the REST API as integers in view requests

Given this code:

$key = "1";
$result = $cb->view("design", "view", array("key"=>$key));

The PHP library will serialize this to a REST request as follows:

GET /bucket/_design/design/_view/view?key=1

This will be deserialized by couchbase as the integer value 1, not as the string value "1". Consequently, any key that is a string of decimal digits cannot be retrieved from a view with the PHP library.

This workaround can be used:

$key = "1";
$result = $cb->view("design", "view", array("key"=>'"'.$key.'"'));

The library will serialize this to a REST request as follows:

GET /bucket/_design/design/_view/view?key="1"

And couchbase will deserialize this as the string value "1".
