PHP extension

This page is about the development of PHP extension in C++.

Macros definitions which seems to be needed for compilation under Windows :

• ZEND_WIN32_FORCE_INLINE,
• ZEND_WIN32=1,
• PHP_WIN32=1,
• __STDC_LIMIT_MACROS,
• ZEND_DEBUG=0,
• ZTS.

The last one is only needed to compile in TS mode, not for the NTS mode.

You have to link against <php>/Release_TS/php5ts.lib (obviously for the thread-safe version).

You have to :

• create a .ini file in /etc/php5/mods-available which contains extension=<extension-name>.<libext>, <libext> being the dynamic library extension for the concerned OS,
• launch as root php5enmod <extension_name>.

In order for the extension yo be recognized, verify that :

• the extension correspondent library <extension_name>.<libext> is present in the extension directory,
• there is a .ini file in the /etc/php5/mods-available directory which contains the line extension=<extension-name>.<libext>,
• there is a link in the conf.d directory pointing to the above file.

• For the directory of the extensions : php-config | grep extension,
• for the .ini file php --ini.
