error_log not working as expected

I have the following basic code:

<?php

    //http://localhost/error_log.php
    echo "write to the error_log";
    error_log("error_log entry");
    //error_log("error_log entry",0);

?>

When I navigate to this page, I see write to the error_log in the browser. It even appears in the access_log /var/log/apache2/access.log.

[my ip here] - - [18/Jan/2013:09:18:54 +0000] "GET /error_log.php HTTP/1.1" 200 314 "-" "Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11"

but when I check the error_log i.e. /var/log/apache2/error.log, I don't see either of the error_log messages.

Why are these not getting entered into the error_log?

error.log does not log anything unless error_log.php page makes an error.

access.log loges all the events that Apache Server process

That is the reason why your error.log does not log the event

check http://httpd.apache.org/docs/2.2/logs.html for more info

You call it without a second parameter, this means default is 0

0   message is sent to PHP's system logger, using the Operating System's system logging mechanism or a file, depending on what the error_log configuration directive is set to. This is the default option.

Now it depends on the configuration of error_log.

If here is not "stderr", php will not log into the apache error log.

It seams to be "syslog" of this php send your log message to the syslog.

Now it depends on how you rsyslog.d is configurated.

But have look at folling logs

tail /var/log/syslog
tail /var/log/messages
tail /var/log/php
tail /var/log/php.log

You message should be in one of them.
