What need to do for supporting a new extension?

[陈雄 <cx282694@xxxxxxxxx>]

I use Ubuntu 9.10,PHP 5.3.1,apache2.24

I compiled the PHP from php source successfully.

Now I want to build the mbstring module from source. My operations:

shell> cd php src dir/

shell> phpize

shell> .configure

shell> make && sudo make install

shell> echo ectension=mbstring.so >> php.ini 

Now it has built the mbstring.so.

But my php still did not support this module.

I found something in the log files of Apache Httpd server.

"PHP Startup: mbstring: Unable to initialize module

 51 Module compiled with module API=20060613

 52 PHP    compiled with module API=20090626

 53 These options need to match "

It seems so strange:

why the module APIS are different when I build the PHP and PHP modules from the same php source tar file.

another question:

If I want to increase a dynamic module for PHP, What do I need to do?

1.setting the php.ini file

2.move the *.so files to the specified directory(extension_dir)

3.move the related headers to include directory( is this necessary?)

is this enough for finishing that task( to support a module)?
