Is there any log file

[sliderman]

Hay,

I'm developping an application in php mysql. My source code is a real mess. In order to debug more efficiently, I wonder know if tghere's any log files (for example for mysql).

Thanks for answers

Most of your previous post have been Linux related - are you saying now that this question is related to XAMPP for Windows?

[sliderman]

yes, that's why I have posted this message on a windows related forum.
for a little explanaition, I'm runnin g under Windows at my job (unfortunately for me) and under unix systems (most of time linux) at my home

The reason I asked was that paths are different in Window to Linux.

In Windows the path would be something like this:
C:\xampp\mysql\data

Look for the log files in there, some will not have a file extension and so would need to be dragged into your text editor for reading.

Usually the file you want would be your Windows logged in user name followed by an err file extension - izzy.err for example - but I doubt that the error logs would help with debugging php.

For debugging php you would use stronger error reporting code in your script and these links may help:

http://us2.php.net/manual/en/function.error-log.php
http://us2.php.net/manual/en/ref.errorfunc.php

These Google searches might have some helpful results for you:

but there is no log file here

For your information, if it might assist, my log file is named by the PC's name, being "stws01.err". It is at the location Izzy referred to.

Also, it logs startup and shutdown, regardless of whether I make a connection.

tanks, my log file is named as file.err (I don't know why 'err' as the extension)

but there is no log for queries, just error

oki
but I fuind this stange. A log file is not commonly file.log, under linux (my production web server) the log file is named mysql.log.

(never heard of google.com ?)

such ironic is this remark !

[Wiedmann]

my log file is named as file.err (I don't know why 'err' as the extension)

Because that's the default file extension for this file (also on *nix):

You can specify where mysqld writes the error log with the --log-error[=file_name] option. If no file_name value is given, mysqld uses the name host_name.err by default and writes the file in the data directory

but it just the error log

[Wiedmann]

but it just the error log

Right, I've answered only your question: Why is the name "*.err".

but there is no log for queries,

If you need the general query log during debugging your script, just add a line with "log" to your "my.cnf" (section "mysqld").
