HI i need to output a JSON object for consuming in iphone
i am able to output like
{"feed":{"id":"1","player":"player1"}}
{"feed":{"id":"1","player":"player2"}}
{"feed":{"id":"2","player":"player3"}}
The code :
$query = "SELECT id,player FROM MyVideos";
$result = mysql_query($query,$link) or die('Errant query: '.$query);
$players[] = array();
if(mysql_num_rows($result)){
while($player = mysql_fetch_assoc($result)){
$players[] = array('player'=>$player);
echo json_encode(array("feed"=>$player));
}
}
But i need to output some thing like this
{"feed":
{"id":"1","player":"player1"},
{"id":"1","player":"player2"},
{"id":"2","player":"player3"}
}
Can anyone please help me with this.

The output you posted isn't valid JSON, you need to put brackets around the items in feed:
{"feed": [
{"id":"1","player":"player1"},
{"id":"1","player":"player2"},
{"id":"2","player":"player3"}

You should loop through your results and build an array of your feed items, and then output it all at once, like this:
$feed_items = array();
if (mysql_num_rows($result)) {
while ($player = mysql_fetch_assoc($result)){
$feed_items[] = $player;
}
}
echo json_encode(array("feed" => $feed_items));
