MySQL:
for ($i = 0; $i<$numfields; $i += 1) {
$field = mysql_fetch_field($query, $i);
echo '<td>' . substr($fielddata[$field->name],0,100) . '</td>';
}

MySQLI:
for ($i = 0; $i<$numfields; $i += 1) {
$field = mysqli_fetch_field($query, $i);
echo '<td>' . substr($fielddata[$field->name],0,100) . '</td>';

Yeah, Fixed, The final code was
for ($i = 0; $i<$numfields; $i += 1) {
$field = mysqli_fetch_field($query, $i);
echo '<td>' . substr($fielddata[$i],0,100) . '</td>';
}
