<reference id="ref.bcompiler">
<title>PHP bytecode Compiler</title>
<titleabbrev>bcompiler</titleabbrev>
<partintro>
<section id="bcompiler.intro">
&reftitle.intro;
&warn.experimental;
<para>
Bcompiler was written for two reasons:
<simplelist>
<member>To encode some classes in a proprietary PHP application</member>
<member>
To enable the production of php-gtk applications that could be used on
client desktops, without the need for a php.exe.
</member>
<member>To do the feasibility study for a PHP to C converter</member>
</simplelist>
The first of these goals is achieved using the
<function>bcompiler_write_header</function>,
<function>bcompiler_write_class</function>,
<function>bcompiler_write_footer</function>,
<function>bcompiler_read</function>,
and <function>bcompiler_load</function> functions. The bytecode files can
be written as either uncompressed or plain. The
<function>bcompiler_load</function> reads a bzip compressed bytecode file,
which tends to be 1/3 of the size of the original file.
</para>
<para>
To create EXE type files, bcompiler has to be used with a modified sapi
file or a version of PHP which has been compiled as a shared library. In
this scenario, bcompiler reads the compressed bytecode from the end of the
exe file.
</para>
<para>
bcompiler is unlikely to improve performance very much, as it only
bypasses the compiler stage of the PHP running process and replaces it
with the import process in bcompiler. It also does not do any bytecode
optimization, this could be added in the future.
</para>
<para>
In terms of code protection, it is safe to say that it would be impossible
to recreate the exact source code that it was built from, and without the
accompanying source code comments. It would effectively be useless to use
the bcompiler bytecodes to recreate and modify a class. However it is
possible to retrieve data from a bcompiled bytecode file - so don't put
your private passwords or anything in it.
</para>

&warn.experimental.func;
<para>
This reads the bytecodes from PHP for an existing function, and writes
them to the open file handle. Order is not important, (eg. if function b
uses function a, and you compile it like the example below, it will
work perfectly OK)
