And let me present an alternative perspective. Never do something like: <?php echo 'Hellow world'; ?> Let Apache (or whatever) interpret HTML as HTML, and don't make it interpret PHP code as HTML. Instead, do: <h1>Hello world</h1> If you're going to use PHP in the middle of a bunch of HTML, then only use it where it's needed: <h1>Hello <?php echo $name; ?></h1> The contents of the PHP $name variable can't be seen by the HTML, which is why you need to enclose it in a little PHP "island". Naturally, if you're going to put PHP code in the middle of a HTML page, make the extension PHP. Otherwise, Apache will not interpret the PHP code as PHP (unless you do some messing with .htaccess or whatever). It's just simplest to call a file something.php if it has PHP in it. Paul -- Paul M.

Paul: I agree with you. My example was not well thought out. My point was not to mix style elements with data. I should have said: I would consider the following"bad practice": <?php echo("<h1>$whatever</h1>"); ?> Whereas, the following I would consider "good practice". <h1><?php echo("$whatever"); ?></h1> Thanks for keeping me honest.

Unless it's something like this: <?php echo "<h1 class=\"$headerClass\">$whatever</h1>"; ?> Which is unlikely for a header tag, but I know this sort of format gets used a lot by me and others, especially for setting alternate row styles on tables (damn browsers and not supporting alternate rows!)

Hey Ash...Why don't you just use CSS subclassing? <style type="text/css">

    h1.odd {class stuff here}
    h1.even {class stuff here}

</style> then <h1 class="odd"><?php echo $whatever; ?></h1> no escaping, and no need to php your css styles. :) Frank

That's what I do do, but the 'odd' has to come from PHP, as unfortunately, numerical selectors in CSS aren't supported by (AFAIK) any browsers at the moment. So for example, if I was coding for alternate rows in a table, I might do: for($i=0; $i<$some_limit; $i++) {

    $rowClass = ($i % 2 == 0)?'':'class="alternate"';
    print <<<EOP
    <tr $rowClass>
        <td>...</td>
        <td>...</td>
        <td>...</td>
    </tr>

EOP; } As far as such loops go, is this a particular faux pas in regards to the way it's coded? Go on Tedd ;) Ash www.ashleysheridan.co.uk

nice pick-up on the fact you only need to css the alternate row not both odd and even :p
