errors going to log file

I have a Solaris box that has both the binary(for command line) and the so versions of PHP installed and both work great, the only issue is that PHP is now sending errors to the apache error_log and not just sending them out to the browser. I had to do this set up on two machines and on the other it sends the error right to the screen. Any ideas? I'd rather have errors come the to the browser. Setup Apache2.039/PHP 4.2.3(latest stable, that day from snaps.php.net) thanks Jeff
