How to Turn Off an On Screen Warning in PHP
PHP will display errors and warnings on the screen according to the level of error reporting defined in either the "php.ini" file or at runtime using the "error_reporting" function. Errors can be silenced or displayed selectively for notices, warnings and errors using the PHP predefined constants that are part of the PHP core. To turn off an on-screen warning in PHP, you need to set the appropriate error level at runtime.
