Newbie / simple (?) mistake?

[pjlennon]

Hi:
This is my first post.

I believe what I've written below should return "exactly seven" in the browser, but it returns "greater than seven" instead and I don't understand why. In case it matters, I'm coding in BBEdit 5.1 (with Mac line breaks/as opposed to UNIX or Win), and viewing the pages in IE 5.1, again, on a Mac running OS X. The server, too, is Apache on an OS X machine.

<?
$num = 7;
echo ($num == 7) ? "exactly seven" : ($num > 7) ? "greater than seven" : "less than seven";
?>

If this is the wrong way to use the forum please let me know (where I might have been able to find this answer) Thanks,

Peter

Put parenthesis around the next ? : block... your code should look like this:

<?
$num = 7;
echo ($num == 7) ? "exactly seven" : ( ($num > 7) ? "greater than seven" : "less than seven");
?>

The parenthesis tell PHP to evaluate the > and < first and then using the value from that, evaluate the num == expression.

or try this... i think this is what your trying to achieve...?

$num = 7;

if($num == "7")
{
echo "Exactly Seven";
}
elseif($num > "7")
{
echo "Greater than seven";
}
else
{
echo "Less than seven";
}

I saw your reply the day you posted it, and intending to write a lengthy reply later that day, I put off replying immediately. Now, a bit late, I'd still like to say thanks,
