error_log works on WinXP but not on Linux

mp96brbj

I'm trying to log all PHP errors on my site to a file. Here is a sample script:

<?php
ini_set('log_errors', 'On');
ini_set('error_log', '/www/myserver/html/test/errors.log');

print "Hello world";
# This produces an error.
in_array('foo','foo');
?>

It works on my local WinXP machine, but not on the Linux server (with different error_log path, of course).
The errors.log file is right there and has write permission. But no errors get logged.

This is driving me nuts. Anyone know why it's not working?

i don't remember where i got this, but it isn't mine.

$old_error_handler = set_error_handler("userErrorHandler");

function userErrorHandler($errno, $errmsg, $filename, $linenum, $vars) 
{
   // timestamp for the error entry
   $dt = date("Y-m-d H:i:s (T)");

   // define an assoc array of error string
   // in reality the only entries we should
   // consider are 2,8,256,512 and 1024
   $errortype = array (
               1    =>  "Error",
               2    =>  "Warning",
               4    =>  "Parsing Error",
               8    =>  "Notice",
               16  =>  "Core Error",
               32  =>  "Core Warning",
               64  =>  "Compile Error",
               128  =>  "Compile Warning",
               256  =>  "User Error",
               512  =>  "User Warning",
               1024 =>  "User Notice"
               );
   // set of errors for which a var trace will be saved
   $user_errors = array(E_USER_ERROR, E_USER_WARNING, E_USER_NOTICE);

   $err = "<errorentry>\n";
   $err .= "\t<datetime>" . $dt . "</datetime>\n";
   $err .= "\t<errornum>" . $errno . "</errornum>\n";
   $err .= "\t<errortype>" . $errortype[$errno] . "</errortype>\n";
   $err .= "\t<errormsg>" . $errmsg . "</errormsg>\n";
   $err .= "\t<scriptname>" . $filename . "</scriptname>\n";
   $err .= "\t<scriptlinenum>" . $linenum . "</scriptlinenum>\n";

   if (in_array($errno, $user_errors))
       $err .= "\t<vartrace>" . wddx_serialize_value($vars, "Variables") . "</vartrace>\n";
   $err .= "</errorentry>\n\n";

   // for testing
   // echo $err;

   // save to the error log, and e-mail me if there is a critical user error
   error_log($err, 3, LOG_FILE);
   //if ($errno == E_USER_ERROR) mail(ERROR_EMAIL, "Critical Error", $err);
}

Thanks, but I don't want to build an error handler for something that's really supposed to just work.

I've tried it (my original code) on several independent servers, but they all behave the same. What could I be doing wrong?
