This one I understand fine:
# $z is $x divided by $y, unless $y is zero, in which case $z should b
+e zero too
if ( $y == 0 ) {
   $z = 0;
}
else {
   $z = $x / $y;
}

or more succinctly
$z = $y ? $x / $y : 0;

While I know that this works, I don't understand the construction. Probably because I am no brain surgeon, but hey, you don't start by performing quintuple bypasses either... :)

And I understand this even less.

and more succincly still, though thoroughly unreadable:
$z = $y && $x / $y;
