Boost.PHP

Boost.PHP is a set of C++ header files that allows you to create a PHP extension in C++ without any obfuscating ZEND_* / PHP_* macros, like the glorious Boost.Python after which this is loosely designed.

A typical example:

#include "boost/php/module.hpp"
#include "boost/php/function.hpp"
using namespace boost;
class m002_module

    : public php::module,

      public php::function_container {

public:

    class handler

        : public php::module::handler {

    public:

        handler(m002_module* mod)

            :php::module::handler(mod) {}
int add(int a, int b) {
return a + b;
}
int sub(int a, int b) {
return a – b;
}
};
public:

    m002_module(zend_module_entry* entry)

        : php::module(entry) {

        entry→functions =

             defun(“add”, &handler::add).

             defun(“sub”, &handler::sub);

    }

};
#define BOOST_PHP_MODULE_NAME m002

#define BOOST_PHP_MODULE_CAPITALIZED_NAME M002

#define BOOST_PHP_MODULE_VERSION “0.1”

#define BOOST_PHP_MODULE_CLASS_NAME m002_module
#include “boost/php/module_def.hpp”

The above can be compiled by typing the following:

g++ -DCOMPILE_DL_M002 \

    -I.\

    -I/opt/php-5.2/include/php \

    -I/opt/php-5.2/include/php/main \

    -I/opt/php-5.2/include/php/TSRM \

    -I/opt/php-5.2/include/php/Zend \

    -I/opt/php-5.2/include/php/ext \

    -I/opt/php-5.2/include/php/ext/date/lib \

    -g -shared -o m002.so m002.cpp

And the script to run

<?php
for ($i = 0; $i < 10; ++$i) {
    var_dump(add($i, 2), sub($i, 2));
}
?>
yields:
<pre>
int(2)
int(-2)
int(3)
int(-1)
int(4)
int(0)
int(5)
int(1)
int(6)
int(2)
int(7)
int(3)
int(8)
int(4)
int(9)
int(5)
int(10)
int(6)
int(11)
int(7)
</pre>
