runkit Functions

Introduktion

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.

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » https://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.

Krav

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.

Konfiguration under drift

De här funktionernas beteende påverkas av inställningarna i php.ini.

Runkit Configuration Options
Name Default Changeable Changelog
runkit.superglobal "" PHP_INI_PERDIR  
runkit.internal_override "0" PHP_INI_SYSTEM  
For further details and definitions of the PHP_INI_* constants, see the php.ini directives.

Här följer en kort förklaring av konfigurationsdirektiven.

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.

Example#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();
?>
