I don't know about easy to read but it can be done in a roundabout sort of way: 
$a = 5;
$b = 5;
$c = 5;
if ((($a == $b ) + ($a -1)) == $c) { print "yes!!!\n"; }

or better yet: 
# given three equal variables
if (($a == $b ) == ($b == $c)) { print "yes!!!\n"; }

# as pointed out by Sidhekin
# given three different variables
if (($a == $b ) == ($b == $c)) { print "yes!!!\n"; }

# still prints 'yes!!!\n'.  Why?
# both sides evaluate to false or 0, 
# and 0 == 0 evaluates to true

Again, I'm not saying I'd use this... ;0)

Update: Thanks to Sidhekin for pointing out my misstep. It does work with 2 same and 1 different variable. ;0)
