How to Change location of PHP error log

First some important information:

Running Windows Server 2008
PHP Version 5.3.8
Installed in C:\Program Files (x86)\PHP\v5.3\php.ini


Navigate to the PHP folder and open the PHP.ini file.  Be careful because if you screw up this file, PHP won't work anymore.

Navigate to:
[WebPIChanges]
error_log=C:\Windows\temp\php53_errors.log

Change it to:

[WebPIChanges]
;error_log=C:\Windows\temp\php53_errors.log
error_log="C:\some_location\php_errors.log"

This may not work until you restart the php service.  If you restart the IIS Admin Service, it should restart any other service that need restarted.

UPDATE:  I missed a key thing.  You need to add the following to the permissions of the log folder.

domain\users need:

Create Files/ write data Allow
Create Folders / append data Allow
