funkcia zvyknutý konvertovať pole [closed] - php, arrays, function

Chcel by som previesť prijatú (modelovú) hodnotu produktu na pôvodnú hodnotu modelu, ale zdá sa, že moja funkcia nefunguje

teraz si nie som istý, čo robím zle

jeho funkcia function identifierToString($DEVICE_PRODUCT){

xml_parser_free($xml);

Keď budú údaje presmerované na ďalšiu stránku, stále dostávam neprevedenú hodnotu

Naozaj nemám zmysel mať pre to funkciu. Snažil som sa vyčistiť pár špagiet ....
