Creating directory mk4php
Creating basic files: config.m4 config.w32 .cvsignore mk4php.c php_mk4php.h CREDITS EXPERIMENTAL tests/001.phpt mk4php.php [done].
To use your new extension, you will have to execute the following steps:
1.  $ cd ..
2.  $ vi ext/mk4php/config.m4
3.  $ ./buildconf
4.  $ ./configure --[with|enable]-mk4php
5.  $ make
6.  $ ./php -f ext/mk4php/mk4php.php
7.  $ vi ext/mk4php/mk4php.c
8.  $ make
Repeat steps 3-6 until you are satisfied with ext/mk4php/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
