In_array dont work with $term_id - php

Question

I am making a code that grab a url part, take values and then set on list.
Problem is on list
if (in_array($term->term_id, $regions)) {
$selected_region = 'selected';
}
else {
$selected_region = 'not';
}
This code does work, always return not.
if ($term->term_id == 2) {
$selected_region = 'varbut?';
}
This work.
$regions is variable and return this:
array(2) { [0]=> string(2) "17" [1]=> string(1) "2" }
Where is the problem to use $term_id?
$term_id with var_dump returns int(17) int(2)
On other pages, single page with only one term is working and code is this:
<?php
$id = get_the_ID();
$postterms = wp_get_post_terms($id, 'destinations'); // get post terms
$parentId = $postterms[0]->term_id; // get parent term ID
?>
<?php if (!in_array($parentId, $regions)): ?>
Why is not working on that selected function? int and string values?
Here is a full term get code:
$custom_terms = get_terms(array($taxonomies), $args);
foreach($custom_terms as $term){
if (in_array($term->term_id, $regions)) {
$selected_region = 'selected';
}
else {
$selected_region = 'not';
}
if ($term->term_id == 2) {
$selected_region = 'varbut?';
}
echo $selected_region;
var_dump($term->term_id);
}
}

Answer 1

It's like you said;
$regions : array(2) { [0]=> string(2) "17" [1]=> string(1) "2" }
$term->term_id : int(2)
How about converting your $regions to ints?
