i want send string array php json , retrieve there.

string[] books = {"book1", "book2", "book3", "book4",..}; 

in json:

list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>; namevaluepairs.add(new basicnamevaluepair("books", books)); httppost.setentity(new urlencodedformentity(namevaluepairs)); ... 

in php side:

$book1 = $result[0]; 

$jsonstring = '["xxx@gmail.com","yy@gmail.com","rr@gmail.com"]'; $arrayofyouremails=json_decode($jsonstring);
