Unable to set upload_tmp_dir on IIS

Question

So I'm trying to set the php upload_tmp_dir setting on an IIS machine.

I changed the setting in php.ini but phpinfo() still shows the default folder. I checked the permissions of IIS_IUSRS who have write, read, modify, etc.

I also ran this to check if the new folder was writable:

$filename = 'C:\inetpub\temp\uploads';
if (is_writable($filename)) {
    echo $filename . ' is writable';
} else {
    echo $filename . ' is not writable';
}

I changed the max_file_uploads value to test if the PHP config being loaded was the most up-to-date, and it was.

What am I missing?

Solution 1

And it turned out the php.ini config file had duplicate entries for upload_tmp_dir, the last of which was the default folderc:\windows\temp. I commented that setting out and everything is now fine.

This thread got me to check for that.

Solution 2

If you look towards the bottom of the file you will find this.

[WebPIChanges]
error_log=C:\Windows\temp\PHP54_errors.log
upload_tmp_dir=C:\Windows\temp
session.save_path=C:\Windows\temp
cgi.force_redirect=0
cgi.fix_pathinfo=1
fastcgi.impersonate=1
fastcgi.logging=0
max_execution_time=300
date.timezone=America/New_York
extension_dir="C:\Program Files (x86)\PHP\v5.4\ext\"

Chance the temp directory here too or comment it out.
