Runtime Configuration
The behaviour of these functions is affected by settings in php.ini.
| Name | Default | Changeable | Changelog |
|---|---|---|---|
| runkit.superglobal | "" | PHP_INI_PERDIR | |
| runkit.internal_override | "0" | PHP_INI_SYSTEM |
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 boolean
- Enables ability to modify/rename/remove internal functions.
