Variables not printing in HTML

[Robert]

In the middle of an HTML document, I am adding some php code to display
some text only if a variable is set. Here is my code:

<?

$people = $_POST['people'];
$people_fee= $people * 10;

$people_text='< tr bgcolor="#fffff f">
<td valign="top"wid th="25%"><font size="2" color="black"
face="arial">Ex tra people</td>
<td valign="top" width="60%" align="left"><f ont size="2"
color="black" face="arial">An alysis of, or compatibility with, <?
print($people); ?> other person(s) (first person included without
charge)
</td>
<td valign="top" width="15%" align="left"><f ont size="2" color="black"
face="arial"><? print( $people_fee)?>< br>
</td>
</tr>';

if ($people) {
print ($people_text);
}
?>


The above partially works. If $people has anything in it, the HTML
displays the text saying "Extra people," etc. But the value of $people
and $people_fee do not print out. Why is this?

Thank you.

You're trying to embed PHP inside a PHP string - this won't then execute as
PHP, it'll just come out as <?print ... etc., which looks like an unknown tag,
which browsers will then just ignore.

If you want variable's value in the string, then either:

(a) Use double quotes, and lose the '<?print(' and '?>'
(b) Concatenate it in, i.e.

$people_text = '...arial">' . $people_fee . '<br>...';
[color=blue]
></td>

Have a look at the generated HTML code, it should give you an idea
what's wrong.
