MongoDBRef::isRef
(PECL mongo >= 0.9.0)
MongoDBRef::isRef — Checks if an array is a database reference
Description
This method does not actually follow the reference, so it does not determine if it is
broken or not. It merely checks that ref is in valid
database reference format (in that it is an object or array with $ref and $id
fields).
Parameters
-
ref -
Array or object to check.
Return Values
Returns TRUE on success or FALSE on failure.
