indenting

Jean Pion

Dear readers,

If you use some funtion to generate html code like:

<?
function display_stuff( parameters)
{
echo "<p>\n";
echo " <table cellspacing=\"0\" cellpadding=\"0\" border=\"0\"
width=\"100%\">\n";
/* .. more stuff here... */
echo " </table>\n";
echo "</p>\n";
}
?>

Is there some way to know your 'current horizontal position' so you can
indent a html section properly?

Tia, Jean

Ugh.

You may want to use Output Buffering along with the Tidy functions.

(And - indenting HTML code is not as important as making clean,
standards-compliant, valid HTML code).

Tia, Jean

As Iván alludes to, the great thing about php is you're really writing a
program, not html. So, in the php commands you'll want neat code. That
will benefit you when you go back to it. I would recommend also
including comments about what is going on, so you don't have to try to
remember 6 months from now. But the only reason to generate neat html
is so the users can look at the page source and make sense of it more.

When I care about indentation (which is not very often), I tend to achieve
it by passing an $indent parameter to the function, which takes a string
of whitespace and prepends it to each line.

Example follows...

================================================

<?php

function createDiv ($innerText, $indent='')
{
$innerText = str_replace("\n", "\n{$indent} ", $innerText);
return "{$indent}<div>\n"
. "{$indent} {$innerText}\n"
. "{$indent}</div>";
}

$divInner = createDiv("Hello world");
$divMiddle = createDiv($divInner);
$divOuter = createDiv($divMiddle, ' ');

?>
<html>
<body>
<?= $divOuter ?>

</body>
</html>

================================================

Which should generate:

<html>
<body>
<div>
<div>
<div>
Hello
</div>
</div>
</div>
</body>
</html>

Besides, a developer should not read raw HTML, but should have a look at the
DOM tree - there are wonderful DOM tree inspectors for Konqueror and
Firefox (built-in) and for IE (via third-party toolbars).

Analyzing the DOM tree generated by the PHP scripts, and validating the
generated HTML against W3C's validators would prove more useful than
writing scripts that generate indented HTML.

(In fact, my programs generate a gibberish of (X)HTML that validates quite
nicely, but is a mess to read).

I'm just working on some inherited code, and I don't want to rewrite it
completely.
What I do now is load source of the resulting page into CSE Html Validator.
If would help me a bit to make it more readable;
but you are right: a comment blocks will do fine.

Thanks for your input,
Jean.
