PHPv5.2.5发布_PHP教程

php(做为现在的主流开发语言)是一种新型的cgi(现在已经不多人在用了)程序编写语言,易学易用,运行速度快,可以方便快捷地编写出功能强大,运行速度快,并可同时运行于 Windows、Unix、Linux平台的Web后台程序,内置了对文件上传、密码认证、Cookies操作、邮件收发、动态GIF生成等功能,php(做为现在的主流开发语言) 直接为很多数据库提供原本的连接,包括Oracle(大型网站数据库平台)、Sybase、Postgres、MySQL(和PHP搭配之最佳组合)、Informix、Dbase、Solid、 access(小型网站之最爱)等,完全支持ODBC接口,用户更换平台时,无需变换php(做为现在的主流开发语言)代码,可即拿即用.
