CXXVII. runkit Functions
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.
進一步訊息例如新版本,下載,源程式,維護者訊息以及更新日誌可以在此找到:
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.
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.
這些函數的行為受 php.ini 的影響。
表格 1. Runkit Configuration Options Name | Default | Changeable | Changelog |
---|
runkit.superglobal | | PHP_INI_PERDIR | | runkit.internal_override | | PHP_INI_SYSTEM | |
有關 PHP_INI_* 常量進一步的細節與定義參見 附錄 G。
以下是配置選項的簡要解釋。
- 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.
例子 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(); ?>

以下常量由本增加模組定義,因此只有在本增加模組被編譯到
PHP 中,或是在運行時被動態加載後才有效。 - RUNKIT_IMPORT_FUNCTIONS
(integer)
runkit_import() flag indicating
that normal functions should be imported from the
specified file.
- RUNKIT_IMPORT_CLASS_METHODS
(integer)
runkit_import() flag indicating
that class methods should be imported from the
specified file.
- RUNKIT_IMPORT_CLASS_CONSTS
(integer)
runkit_import() flag indicating
that class constants should be imported from the
specified file. Note that this flag is only meaningful
in PHP versions 5.1.0 and above.
- RUNKIT_IMPORT_CLASS_PROPS
(integer)
runkit_import() flag indicating
that class standard properties should be imported
from the specified file.
- RUNKIT_IMPORT_CLASSES
(integer)
runkit_import() flag representing
a bitwise OR of the RUNKIT_IMPORT_CLASS_*
constants.
- RUNKIT_IMPORT_OVERRIDE
(integer)
runkit_import() flag indicating that
if any of the imported functions, methods, constants,
or properties already exist, they should be replaced with
the new definitions. If this flag is not set, then any
imported definitions which already exist will be discarded.
- RUNKIT_ACC_PUBLIC
(integer)
PHP5 specific flag to runkit_method_add()
- RUNKIT_ACC_PROTECTED
(integer)
PHP5 specific flag to runkit_method_add()
- RUNKIT_ACC_PRIVATE
(integer)
PHP5 specific flag to runkit_method_add()
- CLASSKIT_ACC_PUBLIC
(integer)
PHP5 specific flag to classkit_method_add()
Only defined when classkit compatibility is enabled.
- CLASSKIT_ACC_PROTECTED
(integer)
PHP5 specific flag to classkit_method_add()
Only defined when classkit compatibility is enabled.
- CLASSKIT_ACC_PRIVATE
(integer)
PHP5 specific flag to classkit_method_add()
Only defined when classkit compatibility is enabled.
- CLASSKIT_AGGREGATE_OVERRIDE
(integer)
PHP5 specific flag to classkit_import()
Only defined when classkit compatibility is enabled.
- RUNKIT_VERSION
(string)
Defined to the current version of the runkit package.
- CLASSKIT_VERSION
(string)
Defined to the current version of the runkit package.
Only defined when classkit compatibility is enabled.
