That's not what the coding standards say. They just talk about private.

I agree. And that's exactly why protected should be underscored.
Example...
<?php
// --- code written by PEAR developer ---
class a {
protected $y = "why\n";
}
class b extends a {
function z() {
echo $this->y;
}
}
// --- code written by end user ---
$b = new b;
$b->z();
$a = new a;
echo $a->y;
/*
* OUTPUT
* why
* Fatal error: Cannot access private property a::$y ...
*/
?>
