PHP扩展生成器
~/public_html/php-5.3.13/ext> ./ext_skel --extname=sample11
Creating directory sample11
Creating basic files: config.m4 config.w32 .svnignore sample11.c php_sample11.h CREDITS EXPERIMENTAL tests/001.phpt sample11.php [done].
To use your new extension, you will have to execute the following steps:
1. $ cd ..
2. $ vi ext/sample11/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-sample11
5. $ make
6. $ ./php -f ext/sample11/sample11.php
7. $ vi ext/sample11/sample11.c
8. $ make
Repeat steps 3-6 until you are satisfied with ext/sample11/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.
第二种方法：使用CodeGen_PECL。
/usr/local/services/php/bin> sudo ./pear install CodeGen_PECL

/usr/local/services/php/bin> sudo ln -s /usr/local/services/php/bin/pecl-gen /usr/local/bin/
~/public_html/php-5.3.13/ext> pecl-gen --extname=sample12

Your extension has been created in directory ./sample12.
See ./sample12/README and/or ./sample12/INSTALL for further instructions.
注：报错“Strict Standards: Declaration of […] should be compatible with that of […] in […]”是因为PHP5.3.0+要求子类声明必须在父类声明，请直接修改php.ini。
error_reporting = E_ALL & ~E_STRICT
以上只是给出了生成PHP扩展的最简单的命令，ext_skel和pecl-gen还支持多种参数生成更加丰富的扩展，请自行参考相关帮助文档。
