这里有新鲜出炉的PHP面向对象编程,程序狗速度看过来!

PHP开源脚本语言

PHP(外文名: Hypertext Preprocessor,中文名:“超文本预处理器”)是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点,入门门槛较低,易于学习,使用广泛,主要适用于Web开发领域。PHP的文件后缀名为php。


7.2.0 beta1 发布了。PHP(PHP:Hypertext Preprocessor)是一种在电脑上执行的脚本语言,主要是用途在于处理动态网页,也包含了命令列执行接口(command line interface),或者产生图形使用者接口(GUI)程式。改进日志如下:
