如何使用PHP获取JSON格式

Question

{  
   "apple":[  
      "get",
      "get me an apple"
   ],
   "orange":[  
      "get me one",
      "get some"
   ],
   "banana ":[  
      "cut them all",
      "get them"
   ],

}

我怎样才能获得格式？我使用print_r($ sql)打印短语和动作列时的SQL输出; 是 Array ( [phrases] => get [actions] => apple ) Array ( [phrases] => get me an apple [actions] => apple ) Array ( [phrases] => Get me one [actions] => orange ) Array ( [phrases] => Get some [actions] => orange ) Array ( [phrases] => cut them all [actions] => Banana ) Array ( [phrases] => get them [actions] => Banana )

请帮忙.谢谢...

试一试简单:

$tempArray = array();
while($rec = mysql_fetch_assoc($sql)){
    $tempArray[$rec['actions']][] = $rec['phrases'];
}
echo json_encode($tempArray);
