When I view this (the end of a method) on a browser I see the printout of the JSON echo.

JSON echo

[{"0":"2222","id":"2222","1":"john","first":"john","2":"true","last":"true"},{"0":"35","id":"35","1":"Griffin","first":"Griffin","2":"Peter","last":"Peter"},{"0":"40","id":"40","1":"cameron","first":"cameron","2":"Peter","last":"Peter"},{"0":"22","id":"22","1":"Sqgger","first":"Sqgger","2":"Peter","last":"Peter"},{"0":"900","id":"900","1":"sayo","first":"sayo","2":"nara","last":"nara"},{"0":"9000","id":"9000","1":"sayaaao","first":"sayaaao","2":"nara","last":"nara"},{"0":"9001","id":"9001","1":"sayaaao","first":"sayaaao","2":"nara","last":"nara"}]


//Perform query
    $result = mysqli_query($con,"SELECT * FROM User");

    $myJson=array();
    //Parse to array
    while($row = mysqli_fetch_array($result)){
        $myJson[]=$row;
        //echo $row['first'] . " " . $row['last'];
        //echo "<br />";
    }

    //Close connection
    mysqli_close($con);

    //Encode and send response
    echo json_encode($myJson);

But on my iOS app, the data is null when I put it in NSLog (but I see the bytes, but the array shows as 0x0000

NSArray* data=[NSJSONSerialization JSONObjectWithData:webData options:0 error:&error];
    NSLog(@"name = %@",[data objectAtIndex:0]);//Null

Any thoughts? thanks

Could you post the json string fetched from the server? – Kunal Mar 30 '13 at 03:09
Added it first code line – William Falcon Mar 30 '13 at 03:18
does your application crashes with exc_bad_access? If not try printing [[data objectAtIndex:0] valueForKey:@"id"]. – Kunal Mar 30 '13 at 03:25
add the code about webData; You put null data to JSON, maybe that. – LE SANG Mar 30 '13 at 03:26
No crash... Just null... – William Falcon Mar 30 '13 at 03:27
NSLog(@"name = %@",data); What the log? – LE SANG Mar 30 '13 at 03:28
Check you webData. Is that null ? – βhargavḯ Mar 30 '13 at 04:06
