NAME m_delete - remove an index from a mapping SYNTAX mapping m_delete(mapping map, mixed index); DESCRIPTION Remove the entry with index 'index' from mapping 'map', and return the changed mapping. If the mapping does not have an entry with index 'index', the first argument is returned. Note that m_delete changes map destructively and only returns the mapping for compatibility reasons.
