how to use chdir to change to current directory?

问题

I'm trying to include a file from another directory and then change the chdir back to the current/original form.

chdir('/some/path');
include(./file.php);
chdir();//How to I change the directory back to the original form?

Anyway to change the chdir back to where file.php is located? or do I have to do it manually?

回答1:

First you need to store the current path, before changing dirs:

$oldPath = getcwd();
chdir('/some/path');
include(./file.php);
chdir($oldPath);

Why do you need to change dirs in order to include a file?

回答2:

Save the current directory (getcwd) before you chdir. Then chdir back.

回答3:

You can do this way - chdir('../'); But really not sure in correct behavior
