This is how you would write virtually unmaintainable, error-prone, slow code
that very likely also produces invalid HTML after a few changes.
Please don't.
<table>
<?php
foreach ($arr as $line)
{
?>
<tr>
<?php
foreach ($line as $cell)
{
?>
<td><?php echo htmlspecialchars($cell); ?></td>
<?php
}
?>
</tr>
<?php
}
?>
</table>
is just fine (see how the braces and tags align at different columns?).
There is also a more verbose alternative syntax, which you could write as
follows:
<table>
<?php foreach ($arr as $line): ?>
<tr>
<?php foreach ($line as $cell): ?>
<td><?php echo htmlspecialchars($cell); ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>
But currently that does not work well with Eclipse PDT:
