title: PHP error_log: Won't write to specified file
body: <p>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:</p>
  
  <pre>
  error_reporting  =  E_ALL & E_STRICT
  display_errors = Off
  log_errors = On
  error_log = "c:/php5/log/php.log"
  </pre>
  
  <p>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.</p>
  
  <p>Any tips?</p>
