无法在php中以表格格式显示数据

Question

对于初学者问题，我很抱歉，我尝试从数据库中检索数据并以表格格式显示。但只打印表头，而不是实际值。 count变量回显2表示数据存在并正确检索。有人可以帮忙吗？

<?php 
include 'connect.php';
error_reporting(E_ALL ^ E_DEPRECATED);
error_reporting(E_ERROR | E_PARSE);
$sql="SELECT * FROM `resources` as r INNER JOIN  `project_resources` as pr 
ON r.res_id =pr.res_id WHERE project_id='$_POST[project_id]'"; 
$result=mysql_query($sql);

$count=mysql_num_rows($result);

if($result === FALSE) {
die(mysql_error()); 
}
echo "$count";
echo '<table>
<tr>
    <th>Resource ID</th>
    <th>Resource Name</th>
    <th>Email</th>
    <th>Phone Number</th>
    <th>Reporting Manager</th>
    <th>Role</th>
    <th>Designation</th>
</tr>';

while ($row = mysql_fetch_array($result)) {
echo '
    <tr>
        <td>'.$row['res_id'].'</td>
        <td>'.$row['res_name'].'</td>
        <td>'.$row['email'].'</td>
        <td>'.$row['phone_number'].'</td>
        <td>'.$row['reporting_manager'].'</td>
        <td>'.$row['role'].'</td>
        <td>'.$row['designation'].'</td>
    </tr>';

 }

 echo '
</table>';

?>
