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.

Runkit Configuration Options
Name Default Changeable Changelog
runkit.superglobal "" PHP_INI_PERDIR  
runkit.internal_override "0" PHP_INI_SYSTEM  
For flere detaljer og definationer af PHP_INI_* constanterne, se ini_set() dokumentation.

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();
?>
