PHP_APP communication interface-methods for encapsulating communication interfaces

: This article mainly introduces the PHP_APP communication interface-encapsulation of communication interfaces. For more information about PHP tutorials, see. Standard format of communication data:

Code Status code (200,400, etc );

Message prompts (logon failure, data return success, etc );

Data returns data;

1. json encapsulation of communication interfaces

Method: json_encode ($ value );

Note: This function can only accept UTF-8 encoded data. if data in other formats is transmitted, the function returns null;

/** * Press Json Output communication data * @ Param Int $ code Status Code * @ Param String $ message Prompt information * @ Param Array $ data Data * @ Return String */ Public static function json ($ code, $ message = '', $ data = array () {if (! Is_numeric ($ code) return ''; $ result = array ('code' => $ code, 'message' => $ message, 'data' => $ data,); echo json_encode ($ result); exit ;}}?>

2. encapsulate communication interfaces in xml format

Method: php generates xml data;

First, there are two methods to summarize how php generates xml data:

1. assemble it into an xml string;

2. use the system class (DomDocument, XMLWriter, SimpleXML );

/** * Press Xml Output communication data * @ Param Int $ code Status Code * @ Param String $ message Prompt information * @ Param Array $ data Data * @ Return Void */ Public static function xmlEncode ($ code, $ message = '', $ data = array () {$ r =''; if (! Is_numeric ($ code) $ r = ''; $ result = array ('code' => $ code, 'message' => $ message, 'data' => $ data,); header ("Content-Type: text/xml"); $ xml =" \ N "; $ xml. =" \ N "; $ xml. = self :: XmlToEncode($ Result); $ xml. =" "; $ R = $ xml; echo $ r;} public static function xmlToEncode ($ data) {$ xml = $ attr = ""; foreach ($ data as $ key => $ value) {if (is_numeric ($ key) {$ attr = "id = '{$ key }'"; $ key = 'ITEM';} $ xml. = "<{$ key} {$ attr}>"; $ xml. = is_array ($ value )? Self :: XmlToEncode($ Value): $ value; $ xml. =" \ N ";}return $ xml ;}}?>
