我有MySql数据,我想从iOS获取数据

    <?php
   // Database credentials
   $host = 'localhost'; 
   $db = 'json'; 
   $uid = 'json'; 
   $pwd = 'json1';


    // Connect to the database server   
    $link = mysql_connect($host, $uid, $pwd) or die("Could not connect");

   //select the json database
   mysql_select_db($db) or die("Could not select database");

   // Create an array to hold our results
   $arr = array();
   //Execute the query
   $rs = mysql_query("SELECT id,userid,firstname,lastname,email FROM users");

   // Add the rows to the array 
   while($obj = mysql_fetch_object($rs)) {
   $arr[] = $obj;
   }

   //return the json result. The string users is just a name for the container object. Can be set anything.
   echo '{"users":'.json_encode($arr).'}';

将iOS连接到MySql数据库的最佳方式是什么


请帮忙

是的,这很好,但只需添加

header('Content-Type: application/json');
以使响应是json而不是html

您可以添加一些验证或错误处理,例如

try
{
  //Your DB query part

      // Connect to the database server   
    $link = mysql_connect($host, $uid, $pwd) or die("Could not connect");

   //select the json database
   mysql_select_db($db) or die("Could not select database");

   // Create an array to hold our results
   $arr = array();
   //Execute the query
   $rs = mysql_query("SELECT id,userid,firstname,lastname,email FROM users");

   // Add the rows to the array 
   while($obj = mysql_fetch_object($rs)) {
   $arr[] = $obj;
   }

   //return the json result. The string users is just a name for the container object. Can be set anything.


    if(count($arr) >0)
    {
   echo '{"users":'.json_encode($arr).'}';
    }
}

catch(PDOException $e) {

        echo '{"error":{"text":'. $e->getMessage() .'}}';
    }
}

创建一个NSURLConnection类,该类与托管此.php文件的服务器对话,如果您使用JSON解析器或内置的NSJSONSerialization类,则可以为您解析响应。您在这里试图做的是创建iOS应用程序用来与您的db对话的Web服务,特别是查询。如果要扩大规模,您应该尝试实现SLIM或FAT-FREE之类的框架。
