The value of the expression is the value assigned. Since the ! operator
will always return a boolean then the assigned value is going to be a
boolean. So $r will always contain a boolean for the purposes of the
ternary operation.
And it also work if the statement is not ternary

Because he's rotating between boolean values.
$r = true;
$r = !$r;// Now $r is false;
$r = !$r;// Now $r is true;
$r = !$r;// Now $r is false;
$r = !$r;/

That wasn't the reason I pimped Opera though. I would NEVER use IEX as
my development browser. I do all my HTML for Opera, then I check it in

This certainly was NOT a joke. I do use CSS classes. As for using a PHP

Hi Steve:
Easy and simple.
First, keep presentation separate from data. In other words, use css
to define a css-class, like so:

In the following example I show a simple OOP example (because I felt

to do row style cycling. Hopefully you're using a decent browser (almost

As you can see, a bunch of different ways to skin this particular cat.

Add this to your default.css file... Or to the page...
TR.dataRow1 { background-color: #e8f5f7; } /* light */
TR.dataRow2 { background-color: #dce8ea; } /* dark */
Then just do this:

And NEVER hardcode the colors in the page. Use CSS !
Adjust t
thats the key use mod 2 and check if the result is 1 or 0.
