ini_set()

Hello, I was doing some fooling around with the ini_set() function and noticed that my scripts stopped functioning altogether (produced blank output). Furthermore, I checked to make sure we actually used a php.ini file and found that we do not. My question is: When using ini_set() without a php.ini file being present does it set all the wouldbe php.ini settings to nothing, making previously relied upon settings non-existent? Some of things I was trying are below: ini_set('include_path', '.:..:../..:' . DIR_WS_INCLUDES); tug_error_reporting(PHP_ERROR_REPORTING_LEVEL); tug_ini_set('error_log', FILENAME_PHP_ERROR_LOG); tug_ini_set('log_errors', PHP_LOG_ERRORS); tug_ini_set('display_errors', PHP_DISPLAY_ERRORS); tug_ini_set('track_errors', PHP_TRACK_ERRORS); Please CC to my email address as I only receive this list in digest. Thanks! Jacob
