(PHP 7, PHP 8)
get_resources — Returns active resources
Returns an array of all currently active resources, optionally filtered by resource type.
Зауваження: This function is meant for debugging and testing purposes. It is not supposed to be used in production environments, especially not to access or even manipulate resources which are normally not accessible (e.g. the underlying stream resource of SplFileObject instances).
typeIf defined, this will cause get_resources() to only return resources of the given type. A list of resource types is available.
If the string Unknown is provided as
the type, then only resources that are of an unknown type will be
returned.
If omitted, all resources will be returned.
Returns an array of currently active resources, indexed by resource number.
