1. Logger is a PHP class that records onto your harddisk values from your running PHP program. You'll
typically use it as a debugger tool, when step debugging isn't applicable. The class can also be
used in production, as a simple logging solution.
2. This demo contains a sample PHP class, ./LoggerDemo.php. You will first run this class in order to
cause Logger to write values on disk, then you will check the resulting log file.
3. a) ParamsProxy Setup
If you have already setup ParamsProxy on this machine, you may skip this step, in whole or in
part.
Logger is built on top of the ParamsProxy class. Before being able to use the ParamsProxy class,
you must setup a configuration folder. All configuration files will live in here, each placed
under a sub-folder with the same name as the name of the class to be configured.
Under Unix, create this folder:
/home/MyConfig
Under Windows, create this folder:
C:\MyConfig
Open the file ./ParamsProxy_config.xml and fill in the path of the folder just created,
e.g.:
<value>/home/MyConfig/</value>
b) Configuration file
The Logger class sets itself up by reading a configuration file; you must place this file in the
proper location:
i. change into /home/MyConfig (on Unix) or C:\MyConfig (on Windows);
ii. create sub-folder Logger
iii. change into just created sub-folder
iv. copy provided file ./config.xml as /home/MyConfig/Logger/config.xml (on Unix) or as
C:\MyConfig\Logger\config.xml (on Windows)
c) Logs folder
The Logger class will store all log files under the logs folder, grouping them by contexts. A
context is essentially a sub-folder that groups values that a number of subscribing PHP classes
log. These values, although coming from different classes, go into the same log file. Consult
the ./Logger.html for more information on contexts.
The location of the logs folder is bound to the location of the configuration folder: the two
share the same parent folder. For example, in this demo, the two locations are:
ON UNIX ON WINDOWS
CONFIGURATION FOLDER /home/MyConfig C:\MyConfig
LOGS FOLDER /home/logs C:\logs
Only on Unix: create folder /home/logs and set it full permissions (octal 0777).
d) Completing installation
Point your browser to the LoggerDemo.php file. If you have correctly installed Logger, you should
see a notice, containing the absolute path to the created log file.
Observe the source code of ./LoggerDemo.php and the resulting log entries to get a feeling of
how logging is done. You'll also want to examine the configuration file and the documentation
(./Logger.html) in order to learn how to declare contexts and customize logging output.
