Is php's 'include' a function or a statement?

Question

There are plenty of examples of both on the web. The php manual says \"The include() statement [...]\", which seems contradictory - if it\'s a statement shouldn\'t it not ha

Answer 1

include is a statement : Explain by following eg

// won't work, evaluated as include(('vars.php') == 'OK'), i.e. include('')
if (include('vars.php') == 'OK') {
    echo 'OK';
}

// works
if ((include 'vars.php') == 'OK') {
    echo 'OK';
}
