Why are some PHP errors are not written in the PHP log?

Question

Hello,

On a server I have to take care of, errors from a vhost do not go to the standard PHP error log.

In the php.ini we have

log = /var/log/file

and phpinfo() does not show any difference between the vhost and the whole server.

But the callback function set up by set_error_handler() catches errors which are not in the php log.

Could you help me to find a way to explore?

Regards, Cédric

update : error_reporting is set to E_ALL once and never modified

Answer 1

Perhaps the errors that aren't logged aren't supposed to be logged? The error reporting settings have no effect when set_error_handler is used, hance you see more errors than in the logfile.

Answer 2

I would take a look at error_log, log_error and error_reporting directive in php.ini and also take a look in the httpd.conf because directives can also be added there using "php_admin_value" and others.
