Java类反射应用得非常广泛几乎是所有框架的最核心部分,PHP程序员似乎从不关心反射。尝试着用java的思想去理解php的反射,跟java基本上基本一致。参考了php手册:http://www.php.net/manual/zh/book.reflection.php。微盘交易源码开源,ubuntu目录home,tomcat8安装报错,pthon 爬虫实例,php网站文章发布模板,潜江工程机械seo推广哪里好lzw

Java Reflection (JAVA反射)机制详解
又开始倒分了,有意思吗?
什是PHP的反射机制
也可以叫映射。说直白点,他不仅能克隆到对象,而且可以调用对象的变量甚
至方法,挺强大的。php API5关于与对象有解释,有机会可以看下,类似于
java中的。当然,这种特性,足以证明php与asp还是有很大区别的!
