While there is no definitive method for handling errors since it varies depending on application needs and a developer's style, nonetheless, there are some "best practices" that should be implemented in all PHP applications. WHAT IS AN ERROR? The answer may seem straightforward but actually requires a bit of discussion. An "error" is an expected or unexpected event that occurs when your PHP code is running. An "expected" error can be a database query that returns no result or an html form that is missing values for designated required fields. An "unexpected" error is one that assumes a particular application state which, for some as yet unknown reason, does not exist. The most obvious unexpected error is a database that is not running or a missing file that one of your scripts expects to find. ERROR HANDLING ENVIRONMENT The recommended "best practice" has three parts: The developer should be alerted to all errors, notices, warnings, etc. both during development and when the PHP application goes into production. The developer should be able to choose how to be notified of these problems. No errors, notices, warnings, etc. should ever be displayed to the user. Even in development, errors dumped to the browser can be bad because they can become hidden in the HTML. In production, you should display a generic page that says "System down for maintenance" or some other generic message. At no time do you want to tip off a hacker as to what went wrong, nor do you want to display the details of what went wrong. That information is for you alone. Although some developers feel that errors should be displayed during development and even in a production environment - modified, o
