just wrong.
what happens is:
$b = $a;
$a++;
so the above example actually will print ("10, 10"). understanding this
will also help you understanding the other example of yours. $a++ is
called "post increment" which means incrementing AFTER using the value
of this. of course there is also "pre increment" as of ++$a which will
do the opposite: incrementing the value and then use it for the
expression.
