[Feature Request] Universal examples regardless of browser or CLI

[timint]

It's been extremely handy to use CLI with testing the examples.

I am here proposing a univeral way for both browser and CLI output:

<?php

  error_reporting(E_ALL);
  ini_set('display_errors', 'On');

  // Output handler
  ob_start(function($buffer){
    return (php_sapi_name() != 'cli') ? '<pre>'.htmlspecialchars($buffer).'</pre>' : $buffer;
  });

  // Do your stuff
  // ...

  var_dump('some output');

[timint]

Or, if you are not gonna decorate the example pages then simply display plain text:

<?php

  error_reporting(E_ALL);
  ini_set('display_errors', 'On');

  header('Content-Type: text/plain; charset=utf-8');

  // Do your stuff
  // ...

  var_dump('some output');
