isdbref()

isdbref(<string>)
isobjid(<string>)

isobjid() returns 1 if <string> is the objid of an existing object, and 0 if it is not a full objid or no such object exists.

isdbref() returns 1 if <string> is the dbref or objid of an existing object. A destroyed object’s dbref no longer exists, so isdbref() returns 0 for it.

isdbref examples: dbrefs and objids that do and do not exist
