     for ($i=0;$i<$length;$i++)
     {
         $temp = [];
         foreach ($arrays as $array)
             $temp[] = $array[$i];

<thead>
<tr>
';
for ($i = 0; $i < count($mg); $i++)
  for($j = 0; $j < count($mg); $j++):

endfor;
$html.=
'
</tr>
</table>

I want to make a new line after each 3 column of data. Thank you for helping me

It looks like you're just missing the opening and closing <tr>s, in the outer for loop. You could add the tags like this:

for ($i = 0; $i < count($mg); $i++) {
    $html .= '<tr>'; //open row
    for($j = 0; $j < count($mg); $j++) {
        $html .='<td>'.$mg[$i][$j].'</td>';
    }
    $html .= '</tr>'; //close row
}
