What are the best practices for handling error messages in PHP to avoid confusing users?

When handling error messages in PHP, it is important to provide clear and informative messages to users without revealing sensitive information. One way to achieve this is by using custom error handling functions to catch and display errors in a user-friendly manner. Additionally, it is recommended to log detailed error messages to a secure location for debugging purposes. 

// Custom error handling function
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // Display user-friendly error message
    echo "An error occurred. Please try again later.";
    
    // Log detailed error message to a secure location
    error_log("Error: $errstr in $errfile on line $errline", 0);
}

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

// Trigger an error for testing
trigger_error("This is a test error");
