Logging container --
Log supports different types of data
containers.
'file' - Log_file
Stores data in an arbitrary file on a local file system (local
refers to any file accessible using PHP's filesystem functions).
'mcal' - Log_mcal
Stores data in a calendar application. This requires the
libmcal and mcal PHP
extensions.
'sql' - Log_sql
Stores data in a database using PEAR::DB
'syslog' - Log_syslog
Stores data using syslog on Unix-based systems
or in the Event Log on Windows NT/2000/XP.
'mail' - Log_mail
Sends log messages to a mailbox. The mail is actually sent when
you close() the logger, or when the destructor
is called (when the script is terminated).
'console' - Log_console
Writes log messages to the text console.
