php7 读取php.ini[4]

mwjhw216

1.需要实现的细节

• 　　在php.ini加上
  
• 　　[initest]
  
• 　　initest.username=test
  
• 　　nitest.userage=99
  
• 　　
  
  
• 　　实现一个initest类 ，实现一个ini_echo方法，打印相关内容
  

2.initest扩展
2.1创建类的扩展：
[root@bogon ext]# cd /usr/local/src/php-7.0.3/ext
[root@bogon ext]# ./ext_skel --extname=initest
2.2 修改配置
[root@bogon ext]# vim initest/config.m4
dnl PHP_ARG_WITH(initest, for initest support,
dnl Make sure that the comment is aligned:
dnl [  --with-initest             Include initest support])更改为：
PHP_ARG_WITH(initest, for initest support,
dnl Make sure that the comment is aligned:
[  --with-initest             Include initest support])2.3 实现代码
在php_initest.h中打开全局变量设置块的注释，改成自己相要的变量如下
ZEND_BEGIN_MODULE_GLOBALS(initest)
    zend_long  userage;
    char      *username;ZEND_END_MODULE_GLOBALS(initest)在initest.c打开相关注释，并添加相关代码
ZEND_DECLARE_MODULE_GLOBALS(initest)PHP_INI_BEGIN()
    STD_PHP_INI_ENTRY("initest.userage","1", PHP_INI_ALL, OnUpdateLong, userage, zend_initest_globals, initest_globals)
    STD_PHP_INI_ENTRY("initest.username","username", PHP_INI_ALL, OnUpdateString, username, zend_initest_globals, initest_globals)PHP_INI_END()PHP_MINIT_FUNCTION(initest){
    REGISTER_INI_ENTRIES();
    return SUCCESS;}PHP_MSHUTDOWN_FUNCTION(initest){
    /* uncomment this line if you have INI entries
    UNREGISTER_INI_ENTRIES();
    */
    UNREGISTER_INI_ENTRIES();
    return SUCCESS;}static void php_initest_init_globals(zend_initest_globals *initest_globals){
    //initest_globals->userage = 1;    //initest_globals->username = "testusername";}PHP_FUNCTION(ini_echo){
        php_printf("username:%s\n",INITEST_G(username));
        php_printf("userage:%d\n",INITEST_G(userage));}const zend_function_entry initest_functions[] = {
    PHP_FE(confirm_initest_compiled,    NULL)       /* For testing, remove later. */
    PHP_FE(ini_echo,    NULL)       /* For testing, remove later. */
    PHP_FE_END  /* Must be the last line in initest_functions[] */};2.4 编译
* [root@bogon hello]# [root@localhost person]# ./configure && make && make install2.5 扩展安装
[initest]
initest.userage=99initest.username=test
extension=initest.so2.6 扩展使用
[root@bogon tests]# cat test.php
