<para>

The <literal>require_once</literal> expression is identical to
|
|
<function>require</function> except PHP will check if the file has
|
|
already been included, and if so, not include (require) it again.

<para>

See the <function>include_once</function> documentation for information
|
|
about the <literal>_once</literal> behaviour, and how it differs from
|
|
its non <literal>_once</literal> siblings.
