第一种方法:使用PHP源码包自带的ext_skel工具。
~/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 downloading CodeGen_PECL-1.1.3.tgz ... Starting to download CodeGen_PECL-1.1.3.tgz (102,640 bytes) ........................done: 102,640 bytes install ok: channel://pear.php.net/CodeGen_PECL-1.1.3 /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 Strict Standards: Declaration of CodeGen_PECL_Element_Constant::docFooter() should be compatible with that of CodeGen_Element::docFooter() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Constant.php on line 341 Strict Standards: Declaration of CodeGen_PECL_Element_Resource::hCode() should be compatible with that of CodeGen_Element::hCode() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Resource.php on line 354 Strict Standards: Declaration of CodeGen_PECL_Element_Ini::docFooter() should be compatible with that of CodeGen_Element::docFooter() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Ini.php on line 443 Strict Standards: Declaration of CodeGen_PECL_Element_Logo::hCode() should be compatible with that of CodeGen_Element::hCode() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Logo.php on line 259 Strict Standards: Declaration of CodeGen_PECL_Element_Method::setCode() should be compatible with that of CodeGen_PECL_Element_Function::setCode() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Method.php on line 471 Strict Standards: Declaration of CodeGen_PECL_Element_Stream::hCode() should be compatible with that of CodeGen_Element::hCode() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Stream.php on line 239 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+不允许子类方法签名与父类方法签名不匹配导致的,以上例第一个严格错误提示:
Strict Standards: Declaration of CodeGen_PECL_Element_Constant::docFooter() should be compatible with that of CodeGen_Element::docFooter() in /usr/local/services/php/lib/php/CodeGen/PECL/Element/Constant.php on line 341
如下对比CodeGen_PECL_Element_Constant和CodeGen_Element的docFooter方法的声明的差异:
/usr/local/services/php/lib/php/CodeGen> grep -Rn "class CodeGen_PECL_Element_Constant" . ./PECL/Element/Constant.php:39:class CodeGen_PECL_Element_Constant /usr/local/services/php/lib/php/CodeGen> grep -Rn "class CodeGen_Element" . ./Element.php:33:abstract class CodeGen_Element
// ./PECL/Element/Constant.php 330 /**- 331 * Generate DocBook XML section block footer 332 * 333 * @access public 334 * @param string Extension name 335 * @return string DocBook XML snippet 336 */ 337 static function docFooter() 338 { 339 return " </variablelist>\n"; 340 } 341 } 342 343 ?> // ./Element.php 292 /** 293 * Generate documentation footer block for all elements of this class 294 * 295 * @access public 296 * @param string Extension name 297 * @return string documentation fragment 298 */ 299 static function docFooter($name) 300 { 301 return ""; 302 } 303 304 } 305 306 ?>
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,请参考相关帮助文档。
~/public_html/php-5.3.13/ext> ./ext_skel --help ~/public_html/php-5.3.13/ext> pecl-gen --help其中,pecl-gen支持从XML中导入生成扩展的强大功能,参见文档: CodeGen_PECL - the PHP extension generator
