__construct(string $resource) : mixed
Parameters
- $resource : string
-
The file path to the resource
__toString()
Returns a string representation of the Resource.
public
__toString() : string
This method is necessary to allow for resource de-duplication, for example by means of array_unique(). The string returned need not have a particular meaning, but has to be identical for different ResourceInterface instances referring to the same resource; and it should be unlikely to collide with that of other, unrelated resource instances.
