public static function XML () {header (' content-type:text/xml '); $xml = "<?xml version= ' 1.0 ' encoding = ' UTF-8 '? >\n"; $xml. = "<root>\n"; $xml. = "<code>200</code>\n"; $xml. = "<message> Data return success </message>\n"; $xml. = "<data>\n"; $xml. = "<id>1</id>\n"; $xml. = "<name>singwa</name>\n"; $xml. = "</ Data>\n "; $xml. =" </root> "; echo $xml;}
