WampServer

Hi all,

I got some logs errors and I'm not able to understand what happens on stand alone PC with Wamp and PHP application running all day long 7 x 7.
Unfortunately I'm not a technician and it's hard to me understand what the issue is.
For me php errors are connected to anomalous switch off from users. Maybe data time it's very close to that event.
Can you please have a look to logs and tell me if the error is on application or due to anomalous switch off ?
Many thanks

Hi,

These are all PHP coding errors and nothing to do with WAMPServer

---------------------------------------------------------------------------------------------

OK , but my question was ... Can these errors be generated by a switch off of computer ?

Hi,

Is the error "Undefined variable: _SERVER" due to an untimely shutdown of the PC, I don't know, but I would say that I would be surprised.

The array $_SERVER['key'] is a predefined variable that is relevant to the server and the system environment, the entries being created by the server itself at each server startup. See : [www.php.net]

The only Apache stop not done correctly is this one:
[Wed Jan 01 13:29:38.022070 2020] [mpm_winnt:notice] [pid 3800:tid 396] AH00428: Parent: child process 6040 exited with status 255 -- Restarting.

What can possibly happen during a power outage is that files in caches and pending SQL writes are not written when they are written during a "normal" shutdown. Therefore, it is possible that a php file may be "spoiled".
