  最近在工作中遇到一个问题:a.php程序需要将接收到的数据同时写到“线上运行的正式数据库”和“进行开发调试的测试数据库”。而测试数据库可能经常会面临对表结构、字段、配置信息做调整等问题,很不稳定,发生错误的概率很高,如果用a.php程序同时写“正式数据库”和“测试数据库”,势必影响到线上运行的正式服务。

  于是,我想到用PHP curl扩展库将生成的$data数组post传递一份给b.php程序,然后a.php程序继续往下执行写“正式数据库”的代码。a.php程序将$data数组传递给b.php程序就完事了,至于b.php如何处理,就不关a.php的事了,b.php程序即使写“测试数据库”失败,也不会对a.php程序造成影响。

  按照这种思路,我写了a.php和b.php的代码:

  a.php程序源代码:

  b.php程序源代码:


  备注:这两段代码需要php curl扩展库的支持,查看phpinfo(),如果cURL support  enabled则表示支持curl库。
  1、Windows下的PHP开启curl库支持:
  打开php.ini,将extension=php_curl.dll前的;号去掉。

  2、Linux下的PHP开启curl库支持:
  编译PHP时在./configure后加上 --with-curl
