 ====== Error Handling ======
 Normally, when an error occurs in a PHP script, the error message is inserted into the script's output.  If the error is fatal, the script execution stops.
+===== Production Server Configuration =====
+Make sure to modify the php.ini file as shown below.  This will display a blank page without errors to the user if there is a problem.  You can enable logging to keep track of errors, which is done slightly below these lines.
+  * Note:  Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.
+<code>
+; Print out errors (as a part of the output).  For production web sites,
+; you're strongly encouraged to turn this feature off, and use error logging
+; instead (see below).  Keeping display_errors enabled on a production web site
+; may reveal security information to end users, such as file paths on your Web
+; server, your database schema or other information.
+display_errors = Off
+; Even when display_errors is on, errors that occur during PHP's startup
+; sequence are not displayed.  It's strongly recommended to keep
+; display_startup_errors off, except for when debugging.
+display_startup_errors = Off
