Compiler for the PHP code

Question

My webcode written in PHP and it is running in the interpreted way. My problem is it is not giving the desired performance so want to try the compiler if any.
Please suggest if we have any compiler option available for the PHP code and more important is this new option.

Answer 1

Checkout HipHop by the Facebook guys, it turns PHP into C code and
compiles down to binary.

Have you tried other optimisation techniques first - eg Caching, and
Profiling?? If this is a production environment you might wanna think
about increasing resources or introducing a load balancer (in the case
of PHP based websites)

Answer 2

I am using bcompiler for my projects.
http://pecl.php.net/package/bcompiler

It seems effective.

Answer 3

Please install and use the PECL bcompiler extension. You
will need to use the appropriate version for your php

Answer 4

PHP gets compiled to bytecode on the server before being executed.
You can cache the pre-compiled code with (for example) APC.
Unless your code is several thousand lines of code (or your server
very slow... 486-slow), the compilation phase is not that long.

I think your main problem can be one of:

1- wrong algorithm
2- long waits (database, files, network, etc.)
3- heavy calculations

Solutions:
1- find and use a different algorithm
2- Try to parallelize code (with gearman or similar, or via
pctnl_fork)    
3- rewrite the heavy functions in C, C++ or Go and compile them, then 
call them via PHP extensions or via gearman/fork.
