Get Root method:

This sentence is placed in the root directory include/base.inc, 7 refers to the include length

Define (' M_root ', substr (DirName (__file__), 0,-7));

This is better to write, directory name length change is also valid. DirName () returns the directory path

Define (' M_root ', DirName (dirname (__file__)));


echo M_root. "  This is the root directory "; . is a connector

Include the previous./Plus is good, regardless of the directory name after no/all valid. 163.com./index.php multiple points do not affect

Include_once m_root. ". /include/common.fun.php ";
