        $result = $this->getUser();      

        $dataresult = json_decode($result, true);
        if($dataresult === NULL) {
            echo "<script language = \"javascript\">window.alert(\"\Tidak Ada Data\");";
            echo "javascript:history.back();</script>";
            return false;
        }
        $data['user'] = $dataresult;
        return $data;

        /*init cURL resource */
        $curl = curl_init($url);

        curl_setopt($curl, CURLOPT_URL, $url);

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        $result = curl_exec ($curl);

        //echo $url;echo $result;  die;
        if ($result === FALSE){

            die('Curl failed: ' . curl_error($curl));
        }
        curl_close($curl);
        return $result;

    } 

This is my code in html

<?php
$main_controll = new App_UserManagement_Control_UserManagement();
$data_from_ctr = $main_controll->usermanagement();
?>

<table cellspacing="2" cellpadding="2" border="0" align="left" id="tablecontent">                      
    <thead style="background-color:#eee;">
        <th width="25">#</th>
        <th width="80">Username</th>
        <th width="117">Name</th>
        <th width="117">Company Code</th>
        <th width="117">Company Name</th>
        <th width="80">User Access</th>
        <th width="80">Login Status</th>
        <th width="80">User Status</th>
        <th width="200">Action</th>

    </thead>
    <tbody>
        <?php if($dataresult == NULL): ?>
        <?php $i = 1; foreach ($dataresult as $row): ?>

        <tr>
        <td><?php echo $i++; ?></td>
        <td><?php echo $row ['_user'] ?></td>
        <td><?php echo $row ['_fullName'] ?></td>
        <td><?php echo $row ['_pyrCode'] ?></td>
        <td><?php echo $row ['_desc'] ?></td>
        <td><?php echo $row ['group_user'] ?></td>
        <td><?php echo $row ['_status'] ?></td>
        <td><?php echo $row ['Active'] ?></td>
        <td></td>
        </tr>
          <?php endforeach; ?>
          <?php endif; ?>
    </tbody>
        </table>
        </fieldset>  

This is my message error

Warning: Invalid argument supplied for foreach() 

Solution

if($dataresult == NULL)

Looks wrong. Shouldn't it be:

if($dataresult !== NULL)

? You can't loop through null!

That's not all though. You overwrite $row with your inner loop!

<?php $i = 1; foreach ($dataresult as $row): ?>
        $No=0;
        foreach($data_from_ctr['user'] as $row) {
