PHP Windows - 从路径返回驱动器号[重复]

Question

This question already has an answer here:

• PHP detect (or remove) current drive letter? 2 answers

I'm trying to get the drive letter from a path in PHP windows.

I'm in this directory:

c:\Program Files\Adobe\

and I want to return:

c

What's the best way to do this? Is there an alternative to parse_url(), but for local paths (and usable under Windows?).

Answer 1

Use substr function from php.

$dir = 'c:/...';
$letter = substr($dir,0,1);
