It cannot. However, if you apply array_map() to the arrays returned by
scandir() before merging them, the problem at hand does not occur in the
first place:
$modi = max(
array_map('filemtime',
array_diff(
array_merge(
scandir(__DIR__),
array_map(
function ($e) {
return 'sections' . DIRECTORY_SEPARATOR . $e;
},
scandir('sections')
)
),
array('.', '..')
)
)
);
