关于PHP递归数组代码分析_PHP教程-php教程-PHP中文网

我们大家都知道php是一种html内嵌式的语言，php与微软的asp颇有几分相似，都是一种在服务器端执行的嵌入html文档的脚本语言，语言的风格有类似于c语言，现在被很多的网站编程人员广泛的运用。文章这里详细的介绍一下php递归数组。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$data数组post传递一份给php程序，然后php程序继续往下执行写“正式数据库”的代码。php程序将$data数组传递给php程序就完事了，至于php如何处理，就不关php的事了，php程序即使写“测试数据库”失败，也不会对 php程序造成影响。
