Sending error_log to screen

Hello, For debugging purposes, I have "display_errors = On" in the /etc/php.ini on my development server. I'm trying to use the error_log() function to log errors, however, the string message does not get send to script output (ie. browser), even with "display_errors = on". I can only see the message from error_log() function in the log file. So, is it possible to have a setup where error_log would send the message to the screen output (ie. the browser for web application) ? or am I missing something ? Thank you for any help.
