There are a couple of different elements you’ll want to consider logging: Errors emitted by the PHP engine itself when a core function fails or if code can’t be parsed Custom errors that your application triggers, usually caused by missing or incorrect user input Activities in your application that you may want to analyze at a later time, such as recording when a user account is updated or content in a CMS is updated Configuration Settings Let’s start by surveying how the PHP engine can be configured to display and log error output. These settings are useful to review if you’re setting up a new server or trying to figure out where errors are being logged on a server that someone else has configured. Default Configuration By default, PHP configuration pertaining to errors is found in the following directives within the configuration file php.ini.
