php基础学习-- __FILE__变量获取文件所在目录

?

dirname(dirname(__FILE__));得到的是文件上一层目录名

如：E:\PHP\wamp\www\testSource

str_replace('\\','/',dirname(__FILE__))?;得到的是文件上一层目录名并进行斜杠替换

E:/PHP/wamp/www/testSource

dirname(__FILE__);得到的是文件所在层目录名

str_replace('\\','/',substr(dirname(__FILE__),0,-3));得到的是文件所在层目录名并进行斜杠替换

如：E:/PHP/wamp/www/testSource/src
