PHP is_dir and mkdir not working on mapped network drive

问题

I have mapped my Z: drive to point to a file share on another server on my network in Windows Explorer. I can access the files and read/write just fine there.

When I try to execute mkdir() from PHP, I get a "No such file or directory" error.

As a test, I gave Everyone access to read, write, and execute and it is still not working.

The code I am using:

mkdir('Y:/newfolder/', 0777);

I have also tried mapping the drive again within PHP to no avail:

system('net use Y: "\\DEV01\share" Password1 /user:Administrator /persistent:no>nul 2>&1");
mkdir('Y:/newfolder/', 0777);

Please assist.

Thanks for your advice everyone. It turned out to be a syntax error. In the mapping code. You must map the drive manually within the PHP script like I did above, except you have to escape your backslashes in there. Instead of \\DEV01\share, you must use \\\\DEV01\\share.
