Match two arrays and put post in pending if no IDs match - php

Question

So I'm somewhat confused and need some assistance from the community, so I have a piece of code that I'm working on and I would like to compare two arrays and then if IDs don't match, to put the post in pending state.
I have the following method:
/**
* Update Office titles
*/
function update_office_titles() {
$office_data = build_offices_array();
$compare_ids = [];
foreach ($office_data as $office) {
$compare_ids[] = [
'wp_office_id' => $office['office_id']
];
}
foreach (api_offices_raw() as $api_office_id) {
$compare_ids[] = [
'api_id' => $api_office_id->id
];
}
print_r($compare_ids);
echo 'All of the office titles have been updated';
}
Here, I'm grabbing all the office_id post_meta and getting all the post_meta values in the DB:
foreach ($office_data as $office) {
$compare_ids[] = [
'wp_office_id' => $office['office_id']
];
}
I get the following return:
[243] => Array
(
[wp_office_id] => 3
)
[244] => Array
(
[wp_office_id] => 4
)
Then I have this foreach that loops through an API with IDs:
foreach (api_offices_raw() as $api_office_id) {
$compare_ids[] = [
'api_id' => $api_office_id->id
];
}
I get this output:
[246] => Array
(
[api_id] => 1
)
[247] => Array
(
[api_id] => 3
)
Here is what I was attempting to achieve:
Check api_id's and match them to the wp_office_id key values, if there are matching IDs, don't do nothing, otherwise call a wp_update_post and set the status to pending on $office['post_id'] on all IDs from wp_office_id that don't match.
All help is appreciated!
