PHP script to convert JSON file to XML file

Hello, I need a PHP script to convert a JSON file (I''ve included a sample named [login to view URL]) to an XML file (I've included a sample name [login to view URL]). The script must be compatible with PHP 5.6 and above and PHP 7 and above. The real json file contains more than 2500 records, so the script must manage all the process without causing memory errors or other issues. I need that PHP script will clean and organize the data in this way: - In the JSON file, all the lines that starts with: "QryGroup… must be ignored (I don't need them). - Records like these in the JSON file: "MarchiTrattati": [ "VOLUPTATE", "RATIONE", "RATIONE MD", "MEHERCULE", "PERVERSITAS" ], must become like these in the XML file: <MarchiTrattati>VOLUPTATE, RATIONE, RATIONE MD, MEHERCULE, PERVERSITAS</MarchiTrattati> - When there are multiple values in the JSON Array "Indirizzi": "Indirizzi": [ { "IdLineNum": 1, "CodCliente": "C00234", "Via": "VIA ALZIO, 55", "CAP": "36020", "Citta": "Lorem del Nappa", "Regione": "VEN", "Prov": "VI", "Localita": null, "Tipo": "S", "NomeIndirizzo": "[login to view URL] ALFIO DR. ROSSI| LOREM DEL NAPPA", "Predefinito": false }, { "IdLineNum": 2, "CodCliente": "C00234", "Via": "VIA VITTORIO EMANUELE, 1", "CAP": "35010", "Citta": "San Mario in Gu", "Regione": "VEN", "Prov": "PD", "Localita": null, "Tipo": "S", "NomeIndirizzo": "LOREM ALFIO DR. ROSSI", "Predefinito": true } ] I need to save in the XML file only the one with the value "Predefinito": true Thanks. For any other questions, ask me what you need to know.
