I don't think this is a safe optimization. In the following case it would
output 'b' and not 'a' which is the correct result:
a.php:
b.php:
It is certainly not likely for a constant to be defined twice but PHP
currently just issues a notice and continues with the first constant value.

While it might seem like a good idea to put something like this into
APC it really just creates more problems than it is worth. I belive it
was removed for that very reason; because it was making it difficult
to distinguish opcode cache errors from optimizer errors.

PHP is not the bottleneck of your
program and thus optimization wont get you too much.

Hi,
You might find http://lxr.php.net to be a useful tool to help with finding
definitions in the PHP code base.

It also makes type analysis for potential compile time optimizations much
easier. It reduces the unknowns that occure from functions! This is
something that could be a big help with that.

This is great! I've always wanted to see optional type hinting for PHP.

Hey,
Anyway, I guess I'll elaborate a bit on what I've been doing with data flow
(ish) stuff. Basically I am looking at building a def use graph for each
variable (as I mentioned in my last email). The problems seem to come with
loops and with var vars, evals, and includes (I also haven't worke
Hey Paul,
As always, great information!
Anyway, I've been looking into building a fairly simple def-use system where I
build a graph for each variable in the function local scope (each CV, TMP_VAR,
and VAR). What I'm doing is building a local graph for each variable in each
basic block and th
lso seem like really interesting (from what I have read thus far).

Hi,
I think that there needs to be more feedback from the community on how
projects are going and the way they should go. This might help to curb some
of the problems being discussed where there was a gap between the project
and what the community wants. Feedback would also help the student know h
t
idea. It would really help keep everyone informd as to whats going on.
Also, more detailed project descriptions would be nice. It was kind of hard
to know what to write a proposal on for just a two sentance description of
the project.

Hi,
I wouldn't really worry about the ternary operator too much. These kinds of
micro optimizations really only appear to make a difference in contrived
benchmarks and usually aren't the norm in real life applications. However,
with that said, an optimization is an optimization. Optimizations like
ight see a significant improvement for these cases.

Hi,
My Google Summer of Code project is to develop and release an initial
version on the optimizer originally being developed by Ilia. The optimizer
will be released to PECL as its own extension, however, it will require APC
in order to run.
Ive worked on cleaning up bugs and testing the existing
Hi,
I am working on the optimizer for APC for Google summer of code 2008 with
Derick.
