"", "playerValue" => $ xml-> playerValue. "", "performancevalue" => $ xml-> performancevalue. "", "performancetime" => $ xml-> performancetime. ""); echo json_encode ($ config);} // update the config data if ($ _ GET ["type"] = "update ") {$ xml = simplexml_load_file (".. /c Onfig. xml "); $ xml-> preferTime = $ _ GET [" data "] [" preferTime "]; $ xml-> playerValue = $ _ GET ["data"] ["playerValue"]; $ xml-> performancevalue = $ _ GET ["data"] ["performancevalue"]; $ xml-> performancetime = $ _ GET ["data"] ["performancetime"]; $ xml-> asXML (".. /config. xml "); echo json_encode (" save success!
