Why might a PHP script run without errors on a web application but throw errors in the console when using functions that have been deprecated in PHP 7.0?

When a PHP script runs without errors on a web application but throws errors in the console when using deprecated functions in PHP 7.0, it could be due to error reporting settings being different between the web server and the command line interface. To solve this issue, you can update the error reporting settings in your PHP script to display errors in both environments.

// Set error reporting to display all errors
error_reporting(E_ALL);
ini_set('display_errors', 1);
