PHP code:i have used a array in this.suggest me why type mismatch occuring
<?php
require_once('loader.php');
$imei = $_REQUEST['data1'];
$regID = $_REQUEST['data2'];
//$resultUsers = getRegIDUser($regID);
$resultUsers = getIMEIUser($imei);
if ($resultUsers != false)
$NumOfUsers = mysql_num_rows($resultUsers);
else
$NumOfUsers = 0;
$jsonData = array();
if ($NumOfUsers > 0) {
while ($rowUsers = mysql_fetch_array($resultUsers)) {
$jsonTempData = array();
$jsonTempData['regid'] = $rowUsers["gcm_regid"];
$jsonTempData['name'] = $rowUsers["name"];
