Show sub-data in each data with php - php

Question

I'm trying to solv this issue. I have this php code.
<?php
if (count($Modulos)>0){
for ($x=0; $x<count($Modulos); $x++){
// SOME CODE, to define variables
$controller = 1;
require_once "../controller/moduloController.php";
for ($z=0; $z<count($ActividadesMOD); $z++){
echo $ActividadesMOD[$z]['actividad']. "<br/>";
}
?>
<tr height="35">
<td align="center"> <strong><?php echo $modulo;?> </strong></td>
<td align="center"> <?php echo $encargado[0];?> </td>
<td align="center" valign="middle"> <?php echo $deadline;?>
<a href="javascript:VerDeadline(<?php echo $idmodulo;?>, '4','<?php echo $deadline;?>', '<?php echo $modulo;?>', '<?php echo $finalizado;?>')" onClick="">
<img src="../img/zoom-icon.png" width="17" height="17" align="absbottom">
</a>
</td>
<td align="center"> <strong> <?php echo $avance . " %";?></strong></td>
<td align="center"> <img src="<?php echo $img;?>" width="28" height="15" title="<?php echo $ttl;?>" /> </td>
<td width="7%" align="center"> </td>
</tr>
<?php }
} else { ?>
<tr height="30" style="font-size:11px" >
<td align="center" colspan="5"> [ NO HAY REGISTROS ] </td>
</tr>
<?php } ?>
Result:
Now, each MODULO has ACTIVIDADES (activities) that i need to show below it.
In the image above, it displays the ACTIVITIES from the MODULO 1 and not the other ones.
Taking the example from other page, should be like this:
