How can error logging be configured in PHP to ensure sensitive information is not exposed to remote users?

To prevent sensitive information from being exposed to remote users through error logging in PHP, it is important to configure the error reporting settings to hide error messages containing sensitive information. This can be achieved by setting the error_reporting level to only display critical errors and by customizing the error handling function to log errors without revealing sensitive data. 

// Set error reporting level to only display critical errors
error_reporting(E_ERROR | E_PARSE);

// Custom error handling function to log errors without exposing sensitive information
function customErrorHandling($errno, $errstr, $errfile, $errline) {
    // Log errors to a secure location without exposing sensitive information
    error_log("Error: [$errno] $errstr in $errfile on line $errline", 0);
}

// Set custom error handling function
set_error_handler("customErrorHandling");
