Description:
------------
the openlog function does not return a resource like would do the fopen or any database connection function.

That implementation limits to 1 the simultaneous number of connections possible to syslog and this is problematic when we aim to use syslog with different log locals.

Expected result:
----------------
$syslog_local0 = openlog('foo', LOG_NDELAY, LOG_LOCAL0);
syslog($syslog_local0, LOG_WARNING, "blah");

$syslog_local1 = openlog('bar', LOG_NDELAY, LOG_LOCAL1);
syslog($syslog_local1, LOG_WARNING, "blah blah");

closelog($syslog_local0);
closelog($syslog_local1);

Patch Name: php_syslog_multiple_context.patch
Revision:   1279855421
URL:        http://bugs.php.net/patch-display.php?bug=51118&patch=php_syslog_multiple_context.patch&revision=1279855421

I just attached a patch which should do the trick. I don't know if it'll be 
accepted by the dev team who handle this part of PHP.

openlog() returns a ressource instead of a bool.

closelog() and syslog() have now a last and optional parameter: a context 
ressource.

Everything which was working before, should still work. The only change is the 
return value of openlog() which should be strictely compared (openlog(...) !== 
true).

here is a sample test script:

<?php
  syslog(LOG_ERR, "test 1 on ressource #0");
  // Jul 23 05:20:22 wild php: test 1 on ressource #0

  $r1 = openlog("test syslog #1", LOG_PID, LOG_SYSLOG);
  $r2 = openlog("test syslog #2", LOG_PID, LOG_SYSLOG);
  syslog(LOG_ERR, "test on ressource #1", $r1);
  // Jul 23 05:20:22 wild test syslog #1[24144]: test on ressource #1

  syslog(LOG_ERR, "test on ressource #2", $r2);
  // Jul 23 05:20:22 wild test syslog #2[24144]: test on ressource #2

  closelog($r1);
  closelog($r2);
  syslog(LOG_ERR, "test 2 on ressource #0");
  // Jul 23 05:20:22 wild php[24144]: test 2 on ressource #0

  openlog("test syslog #0", LOG_PID, LOG_SYSLOG);
  syslog(LOG_ERR, "test 3 on ressource #0");
  // Jul 23 05:20:22 wild test syslog #0[24144]: test 3 on ressource #0

  closelog();
  syslog(LOG_ERR, "test 4 on ressource #0");
  // Jul 23 05:20:22 wild php[24144]: test 4 on ressource #0
?>

sorry

When syslog is configured in php fpm error_log, you can't safely use openlog/syslog() anymore, i think we must fix that.
