Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Runkit Configuration Options

Name	Default	Changeable	Changelog
runkit.superglobal	""	INI_PERDIR
runkit.internal_override	"0"	INI_SYSTEM

For further details and definitions of the INI_* modes, see the Where a configuration setting may be set.

Here's a short explanation of the configuration directives.

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();
?>

runkit.internal_override bool

Enables ability to modify/rename/remove internal functions.
