php function Graphics and text develop fast Expand Tutorial of need

需求:比如开发一个叫做 heiyeluren 的扩展,扩展里就一个函数 heiyeluren_test(),输入一个字符串,函数返回:Your input string: xxxxx。
要求:了解C/C++编程,熟悉PHP编程
环境:下载一份php对应版本的源码,我这里是 php-5.2.6,先正常安装php,假设我们的php安装在 /usr/local/php 目录,源码在 /root/soft/php/php-5.2.6/,现在开始!
步骤一:生成扩展框架


cd /root/soft/php/php-5.2.6/ext
./ext_skel --extname=heiyeluren
cd /root/soft/php/php-5.2.6/ext/heiyeluren
vi config.m4
打开文件后去掉 dnl ,获得下面的信息:
PHP_ARG_ENABLE(heiyeluren, whether to enable heiyeluren support,
[  --enable-heiyeluren           Enable heiyeluren support])

保存退出.
(图01)

第二步:编写代码

vi php_heiyeluren.h
找到:PHP_FUNCTION(confirm_heiyeluren_compiled); ,新增一行:
PHP_FUNCTION(heiyeluren_test);
保存退出。
(图02)

vi heiyeluren.c
数组里增加我们的函数,找到 zend_function_entry heiyeluren_functions[],增加:
PHP_FE(heiyeluren, NULL)
(图03)

再到 heiyeluren.c 文件最后面增加如下代码:
PHP_FUNCTION(heiyeluren_test)
{
    char *arg = NULL;
    int arg_len, len;
    char *strg;

    if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s", &arg, &arg_len) == FAILURE) {
        return;
    }

    len = spprintf(&strg, 0, "Your input string: %s\n", arg);
    RETURN_STRINGL(strg, len, 0);
}
保存退出。
(图04)

第三步:编译安装

cd /root/soft/php/php-5.2.6/ext/heiyeluren
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make test
make install

现在看看是不是有个 /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/heiyeluren.so
编辑php.ini,把扩展加入进去:
vi /usr/local/php/lib/php.ini
在[PHP]模块下增加:
extension = heiyeluren.so
保存退出。
(图05)

注意:如果你不存在扩展文件目录,或者安装报错,那么可以自行建立这个目录,然后把扩展拷贝到目录下,然后记得把 php.ini 文件中的 extension_dir 修改为该目录:
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
(图06)

第四步:检查安装结果
现在看看模块加载了没有:
/usr/local/php/bin/php -m,应该会打印出:
[PHP Modules]
...
heiyeluren
...
[Zend Modules]


然后重启apache,输出 phpinfo() ,应该能够看到:
heiyeluren
heiyeluren support enabled

(图07)

看看函数是否存在并且调用,在web目录下建立:heiyeluren.php
echo "

";<br>print_r(get_loaded_extensions());<br>print_r(get_extension_funcs('heiyeluren'));<br>echo heiyeluren_test('My first php extension');<br>echo "
";
?>

访问apache,应该能够看到:
Array
(
    ...
    [33] => heiyeluren
)
Array
(
    [0] => confirm_heiyeluren_compiled
    [1] => heiyeluren_test
)
Your input string: heiyeluren
(图08)
