# CXXXVI. runkit Functions

# Введение

The runkit extension provides means to modify constants, user-defined functions, and user-defined classes. It also provides for custom superglobal variables and embeddable sub-interpreters via sandboxing.

Дополнительная информация, такая как новый версии, скачивание, исходные файлы, информация о разработчике и CHANGELOG, могут быть найдены здесь: http://pecl.php.net/package/runkit.

This package is meant as a feature added replacement for the classkit package. When compiled with the `--enable-runkit=classkit` option to ./configure, it will export classkit compatible function definitions and constants.

# Установка

Это расширение PECL не поставляется вместе с PHP.

Дополнительная информация, такая как новый версии, скачивание, исходные файлы, информация о разработчике и CHANGELOG, могут быть найдены здесь: http://pecl.php.net/package/runkit.

Вы можете скачать DLL этого расширения PECL со страницы PHP Downloads или http://snaps.php.net/.

# Требования

Modifying Constants, Functions, Classes, and Methods works with all releases of PHP 4 and PHP 5. No special requirements are necessary.

Custom Superglobals are only available in PHP 4.2.0 or later.

Sandboxing requires PHP 5.1.0 or later, or PHP 5.0.0 with a special TSRM patch applied. Regardless of which version of PHP is in use it must be compiled with the `--enable-maintainer-zts` option. See the `README` file in the runkit package for additional information.

# Настройка во время выполнения

Поведение этих функций зависит от установок в `php.ini`.

Таблица 1. Runkit Configuration Options

Name | Default | Changeable | Changelog
--- | --- | --- | ---
runkit.superglobal | "" | PHP_INI_PERDIR |
runkit.internal_override | "0" | PHP_INI_SYSTEM |

Для подробного описания констант PHP_INI_*, обратитесь к документации функции ini_set().

Краткое разъяснение конфигурационных директив.

`runkit.superglobal` string

  Comma-separated list of variable names to be treated as superglobals. This value should be set in the systemwide php.ini file, but may work in perdir configuration contexts depending on your SAPI.

  Пример 1. Custom Superglobals with runkit.superglobal=_FOO,_BAR in php.ini

  `<?php
  function show_values() {
  echo "Foo is $_FOO\n";
  echo "Bar is $_BAR\n";
  echo "Baz is $_BAZ\n";
  }
  $_FOO = 'foo';
  $_BAR = 'bar';
  $_BAZ = 'baz';
  /* Displays foo and bar, but not baz */
  show_values();
  ?>`
