How to find out if a urlSegment is inside a PageArray

[ngrmm]

i have a event-page with a table.
first column in this table is page-reference-field

how can i find out if a urlSegment matches one of the rows having the same page-reference-field (page-id)?

// all guests
$allguests = new pageArray();
foreach($page->event_guests_table as $event_guests_table_row) {
	$allguests->prepend($event_table_row->guest);
}

// echo allguests would output: 1101|1102|1103|…
// domain.tld/event/1101/

// show content if guest is in the table or redirect
if($input->urlSegment1 ~= $allguests ) {
	// show content
}
else {
	// redirect
}

 

which selector operator do i have to use? the one above does not work

try has()

$segment = $sanitizer->int($input->urlSegment1);
if($allguests->has($pages->get($segment))) {
    echo "yep";
}

 

[ngrmm]

thx @dragan

this works

if($allguests->has("id=$input->urlSegment1")) {
}

but i'll do it like you suggested. first sanitizing.
