The behaviour of these functions is affected by settings in php.ini.
| Name | Default | Changeable | Changelog | 
|---|---|---|---|
| inclued.enabled | Off | PHP_INI_SYSTEM | |
| inclued.dumpdir | NULL | PHP_INI_SYSTEM | 
Here's a short explanation of the configuration directives.
inclued.enabled
     bool
    Whether or not to enable inclued.
inclued.dumpdir
     string
    Location (path) to the directory that stores inclued files. If set, each PHP request will create a file. These files are serialized versions of what inclued_get_data() would produce, so may be unserialized with unserialize().
Because every request creates a file, this directory may fill up fast!
