php安裝: /usr/local/php
[root@ns root]# phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
[root@ns root]# phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
在/usr/local/src/php-4.3.5/ext下找到這個工具
來建立一個php擴展的一個框架
[root@ns ext]#cd /root/soft/php-5.3.4/ext/
[root@ns ext]# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 .cvsignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].
To use your new extension, you will have to execute the following steps:
1. $ cd ..
2. $ vi ext/my_module/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-my_module
5. $ make
6. $ ./php -f ext/my_module/my_module.php
7. $ vi ext/my_module/my_module.c
8. $ make
執行了這個步驟以後你會看到這樣的結果
Repeat steps 3-6 until you are satisfied with ext/my_module/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.
這樣以後我們會在這個目錄下生成一個目錄叫my_module
進入這裏面我們看看
[root@ns ext]# cd my_module/
[root@ns my_module]# ls
config.m4 EXPERIMENTAL my_module.php tests
CREDITS my_module.c php_my_module.h
然後我們要修改文件順序是
configue.m4
my_module.c
php_my_module.h
使用文本編輯器打開config.m4文件，文件內容大致如下：
dnl $Id$d
dnl config.m4 for extension my_module
dnl don't forget to call PHP_EXTENSION(my_module)
dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.
dnl If your extension references something external, use with:
dnl PHP_ARG_WITH(my_module, for my_module support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_module Include my_module support])
dnl Otherwise use enable:
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])
if test "$PHP_MY_MODULE" != "no"; then
dnl If you will not be testing anything external, like existence of
dnl headers, libraries or functions in them, just uncomment the
dnl following line and you are ready to go.
dnl Write more examples of tests here...
PHP_EXTENSION(my_module, $ext_shared)
Fi
根據你自己的選擇將
dnl PHP_ARG_WITH(my_module, for my_module support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_module Include my_module support])
修改成
PHP_ARG_WITH(my_module, for my_module support,
Make sure that the comment is aligned:
[ --with-my_module Include my_module support])
或者將
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])
修改成
PHP_ARG_ENABLE(my_module, whether to enable my_module support,
Make sure that the comment is aligned:
[ --enable-my_module Enable my_module support])
我這裏用了後者
然後保存退出
然後在編輯
Vi my_module.c
將文件其中的下列代碼進行修改
/* Every user visible function must have an entry in my_module_functions[].
*/
function_entry my_module_functions[] = {
PHP_FE(say_hello, NULL) /* ?添加着一行代碼 */
PHP_FE(confirm_my_module_compiled, NULL) /* For testing, remove later. */
{NULL, NULL, NULL} /* Must be the last line in my_module_functions[] */
};
在文件的最後添加下列代碼
PHP_FUNCTION(say_hello)
{
zend_printf("hello world/n");
}
保存文件退出
然後我們就可以在這個目錄下使用上面的命令了
/usr/local/php/bin/phpize
執行以後會看到下面的
[root@ns my_module]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20020918
Zend Module Api No: 20020429
Zend Extension Api No: 20050606
[root@ns my_module]#
然後執行./configure --enable-my_module --with-apxs=/usr/local/apache/bin/apxs --with-php-config=/usr/local/php/bin/php-config
我們在安裝以後的php的bin目錄下的可以找到這個文件的
php-config 和phpize
這一步驟一定要注意你的apache的apxs放在哪裏了
然後執行make
你會看到出現錯誤了你重新定義了函數我們前面的
這個你在回頭改一下這個文件把原來的函數刪除掉在生成的文件裏面會有同樣的函數
你在加入你的代碼
就可以通過了
這個時候會在當前的目錄下生成一個目錄叫modules他的下面就放着你要的
my_module.so文件
cp modules/my_module.so /usr/local/php/ext/
這裏需要你先設置你的php的擴展目錄的在
在php.ini裏面
通過extension_dir
最後一不是你在php.ini文件中打開這個擴展
extension=my_module.so
然後
重新起動apache
用phpinfo來察看一下ok了
