PHP SimpleXML- funksies
PHP SimpleXML Inleiding
SimpleXML is 'n uitbreiding wat ons toelaat om maklik XML-data te manipuleer en te kry.
SimpleXML bied 'n maklike manier om 'n element se naam, eienskappe en tekstuele inhoud te kry as jy die XML-dokument se struktuur of uitleg ken.
SimpleXML verander 'n XML-dokument in 'n datastruktuur waardeur u kan herhaal soos 'n versameling skikkings en voorwerpe.
