I've heard that the Zend Engine's garage collector is not perfect, so
can someone demonstrate how to create a memory leak in PHP?

ZE doesn't use garbage collector, it implements reference counting
algorithm that is notorious for its inability to handle circular
references. If you have an object A that holds a reference to B, and B
directly or indirectly refers back to A, neither A nor B will be freed
until the script ends.

According to Wikipedia ( http://en.wikipedia.org/wiki/
Reference_counting), reference counting is a form of garbage
collecting.

The nice thing about Wikipedia is that if you find wrong or confusing
information there, you can correct it immediately. ;)

Except in this case it is not wrong or confusing. It is a method of
garbage collection.

Well, I know at least two people who are already confused. ;)
Before starting the next meaningless scholastic discussion about terms,
make sure you do understand how GCs work and what is the difference
between "tracing"/"full-automatic" GCs and reference counting.

Believe me - I know how garbage collection works. I haven't been
programming longer than you've been alive without finding out.
You really need to understand the terminology before you start telling
people they're wrong.

Learn what garbage collection is - then figure it out for yourself. You
seem to think the way Java does it is the only way. It's not.

Did I say "smart polemicist"? Yes indeed, very smart polemicist, strong
but always correct.

Yeah, keep looking down on me. I'm glad I was helpful in raising your
