How can PHP developers improve error handling and reporting in their scripts for better troubleshooting?

PHP developers can improve error handling and reporting in their scripts by using try-catch blocks to catch exceptions and display meaningful error messages to users or log them for troubleshooting. Additionally, developers can utilize error_reporting() function to set the level of error reporting, and use functions like error_log() to log errors to a file for later analysis.

try {
    // Code that may throw an exception
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
    error_log("An error occurred: " . $e->getMessage(), 3, "error.log");
}
