PHP error_log: Won't write to specified file

Question

Running PHP under IIS on my Win XP Pro system. I cannot debug my scripts easily because get PHP to write to the error log I specify. Here are the relevant (I think) php.ini entries:

error_reporting  =  E_ALL & E_STRICT
display_errors = Off
log_errors = On
error_log = "c:/php5/log/php.log"

I had the slashes going the Windows/DOS way before. In either case, it did not write to the file php.log in that directory. The log file is writable by IUSR_SERVERNAME, the directory is writable by IUSR_SERVERNAME, the parent directory is writable by IUSR_SERVERNAME. I'm sure I'm missing something stupid.

Any tips?

I found the problem. I updated my answer. Let me know how it goes — The Disintegrator

Have you tried in the php file itself?

error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', "c:/php5/log/php.log");

Update: The problem is that you are using a bitwise AND where you should use a bitwise OR

Try this

var_dump(E_ALL);
var_dump(E_STRICT);
var_dump(E_ALL | E_STRICT);
var_dump(E_ALL & E_STRICT);

output: int(6143) int(2048) int(8191) int(0)

So basically you are writing

error_reporting  =  0

Effectively turning off the error reporting. Change the & for an | in your php.ini and you should be ok.

Kind of misses the point of having in the INI file, but I'll try it.

Shouldn't it be error_reporting = E_ALL | E_STRICT instead of error_reporting = E_ALL & E_STRICT? & of E_ALL and E_STRICT will return all zeros I think

That was it, thank you very much! Of course, it didn't log an error related to the initial problem, but that's a security issue I have to figure out, not related to the error log.

An interesting side note: I just uncommented the line, so the initial PHP.ini file had it wrong.
