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.
Uddybende information sÃ¥ som nye udgivelser, downloads, kildekoder, vedligeholder information samt en CHANGELOG, kan findes her: » 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.

Systemkrav
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.
Runtime Konfiguration
Virkemåden af disse funktioner er berørt af indstillinger i php.ini.
| Name | Default | Changeable | Changelog |
|---|---|---|---|
| runkit.superglobal | "" | PHP_INI_PERDIR | |
| runkit.internal_override | "0" | PHP_INI_SYSTEM |
Her er en kort forklaring på konfigurations-direktiverne.
- 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();
?>

Konstanterne nedenunder er defineret af denne udvidelse, og vil kun være tilgængelige når denne udvidelse enten er blevet kompileret ind i PHP eller dynamisk indsat under runtime.
- 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)
