Question

Is there a built-in debugging log in PHP, such as Ruby on Rails logger.info (), in the development.log file?

With PHP, I would like to look "under the hood" to find out what happens ... pages, query strings, etc.

I have a bunch, but I can not find anything.

(I am trying to port a web application from RoR to PHP because I need more execution speed.)

PHP has

• error_log - sends an error message to the web server error log, TCP port, or to a file and
• trigger_error - generates an error / warning / notification message at the user level

which you can use to run and register predefined error types , for example

trigger_error( "Custom Warning", E_USER_WARNING );

Third-party libraries exist with

• PEAR
• Zend_Log

. OO:

$logger->log('Informational message', Zend_Log::INFO);

• Log4PHP
