Allows enabling (<literal>"true"</literal>) or disabling

(<literal>"false"</literal>) FFI API usage, or restricting it only to
|
|
the CLI SAPI and preloaded files (<literal>"preload"</literal>).
|
|
</para>
|
|
<para>
|
|
The FFI API restrictions only affect the <classname>FFI</classname> class,
|
|
but not overloaded functions of <classname>FFI\CData</classname> objects.
|
|
This means that it is possible to create some <classname>FFI\CData</classname>
|
|
objects in preloaded files, and then to use these directly in PHP scripts.

Allows preloading of FFI bindings during startup, which is not possible with <methodname>FFI::load</methodname>
|
|
if <link linkend="ini.opcache.preload-user">opcache.preload_user</link> is set.
|
|
This directive accepts a <constant>DIRECTORY_SEPARATOR</constant> delimited list of filenames.
|
|
The preloaded bindings can be accessed by calling <methodname>FFI::scope</methodname>.
