Using log4php with Apache httpd's access_log and/or error_log?

[Raj, Pavan (CCI-Atlanta)]

I am trying to use log4php with a PHP application that runs on Apache 2.2.3. 
When the script is executed using CLI, the log4php bits are invoked correctly 
and log entries are created as expected. But when the script is accessed using 
a web browser, the log file(s) defined in the log4php config are created but 
nothing gets written to them. Where should I look? How do I figure out why 
log4php doesn't write to the log file?

Thanks in advance!
