La expresión <literal>require_once</literal> es idéntica a
|
|
<function>require</function>
|
|
salvo que PHP verifica si el fichero ya ha sido incluido, y si
|
|
es el caso, no lo incluye una segunda vez.

Ver la documentación de <function>include_once</function>
|

para más información sobre el comportamiento de <literal>_once</literal>,
|
|
y lo que lo diferencia de las instrucciones sin <literal>_once</literal>.
