PHP via CLI successfully logs errors to /var/log/php_errors.log.
But apache + php does not log errors.
[bla@notebook ~]$ apachectl -v
Server version: Apache/2.2.17 (Unix)
Server built: May 19 2011 03:15:39
[bla@notebook ~]$ php -v
PHP 5.3.6 with Suhosin-Patch (cli) (built: Mar 23 2011 13:28:00)

In php.ini I have:
display_errors = On
error_reporting = E_ALL | E_STRICT
log_errors = On
error_log = php_errors.log
In httpd.conf:
ErrorLog "/var/log/httpd/error_log"
Permissions:
[bla@notebook /]$ ls -la /var/log/httpd/
-rwxrwxr-x 1 root root 133351 21.11.2011 11:18 access_log*
-rwxrwxr-x 1 root http 1307 21.11.2011 11:18 error_log*
[bla@notebook /]$ ls -la /var/log/php_errors.log
-rwxrwxr-x 1 root http 521 14.11.2011 17:31 /var/log/php_errors.log*
As you can see the Apache daemon has permissions to write into log files.
Still no errors from Apache or PHP in /var/log/php_errors.log and /var/log/httpd/error_log.
UPDATE 1.
Changed this line in php.ini:
error_log = php_errors.log
to full path:
error_log = /var/log/php_errors.log
Permissions were ok. But if someone is also having problems with it, you can debug setting permissions to logfile 0777 or changing file owner.
php_admin_value error_reporting 'E_ALL & ~E_STRICT'
