Disabling PHP Errors on VS

On hosting, it is necessary to disable the display of PHP errors in the browser. Firstly, it scares users and indicates poor website quality; secondly, errors can provide hints to hackers during the process of hacking the site.

Let's disable the display of errors. To start, let's create an error, for example, by outputting a non-existent variable:

php<?php
  echo $test;
?>

Now, let's use ini_set to enable the display of errors and make sure that it is shown in the browser:

php<?php
  ini_set('display_errors', 'on');
  echo $test;
?>

And now let's disable the display of errors and make sure that it is no longer shown:

php<?php
  ini_set('display_errors', 'off');
  echo $test;
?>
