下載php 5.2.6 源碼 并解壓
編譯安裝，搭建php環(huán)境
二，創(chuàng)建擴展項目
進入源碼目錄
cd php5.2.6/ext/
./ext_skel --extname=my_ext
創(chuàng)建名字為my_ext的項目，最終會生成my_ext.so
三，更改配置和程序
$ vi ext/my_ext/config.m4
根據(jù)你自己的選擇將
dnl php_ARG_WITH(my_ext, for my_ext support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_ext Include my_ext support])
修改成
php_ARG_WITH(my_ext, for my_ext support,
Make sure that the comment is aligned:
[ --with-my_ext Include my_ext support])
或者將
dnl php_ARG_ENABLE(my_ext, whether to enable my_ext support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_ext Enable my_ext support])
修改成
php_ARG_ENABLE(my_ext, whether to enable my_ext support,
Make sure that the comment is aligned:
[ --enable-my_ext Enable my_ext support])
$ vi ext/my_ext/php_my_ext.h
將
php_FUNCTION(confirm_my_ext_compiled); /* For testing, remove later. */
更改為
php_FUNCTION(say_hello);
$ vi ext/my_ext/my_ext.c
將
zend_function_entry php5cpp_functions[] = {
php_FE(confirm_my_ext_compiled, NULL) /* For testing, remove later. */
{NULL, NULL, NULL} /* Must be the last line in php5cpp_functions[] */
};
更改為
zend_function_entry php5cpp_functions[] = {
php_FE(say_hello, NULL)
{NULL, NULL, NULL} /* Must be the last line in php5cpp_functions[] */
};
在最后添加：
php_FUNCTION(say_hello)
{
zend_printf("hello world/n");
}
四，編譯
$ cd my_ext
$ /usr/local/php/bin/phpize
ps: 如果出現(xiàn)：Cannot find autoconf.……的錯誤信息，則需要安裝 autoconf (安裝過程略)
$ ./configure --with-php-config=/usr/local/php/bin/php-config
$ make
這時會編譯出 my_ext/modules/my_ext.so
五，配置php.ini
將my_ext.so放入/usr/local/php/ext/目錄
$ vi php.ini
修改添加如下：
extension_dir = '/usr/local/php/ext/'
extension=my_ext.so
六，測試
$ vi test.php
<?php
say_hello();
?>
$ /usr/local/php/bin/php test.php
hello world.
則大功告成
