CXVII. 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.

Требования

Modifying Constants, Functions, Classes, and Methods

works with all releases of PHP4 and PHP 5. No special requirements are

necessary.

Custom Superglobals are only available in PHP4.2.0 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.

Custom Superglobals

The runkit.superglobal ini option may be set to a

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


<?
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();

?>

Предопределенные константы

-Перечисленные ниже константы определены данным расширением и могут быть

доступны только в том случае, если PHP был собран с

поддержкой этого расширения или же в том случае, если

данное расширение подгружается во время выполнения.
