PHP Compare two multidimensional arrays - php

Question

I have two multidimensional arrays like this:
Guest allow array
Array
(
[0] => 5
[1] => 2
[2] => 3
)
and second one like this
Array
(
[0] => Array
(
[property_id] => 6
[guest_allow] => 2
)
[1] => Array
(
[property_id] => 9
[guest_allow] => 3
)
[2] => Array
(
[property_id] => 62
[guest_allow] => 2
)
[3] => Array
(
[property_id] => 72
[guest_allow] => 3
)
[4] => Array
(
[property_id] => 76
[guest_allow] => 4
)
[5] => Array
(
[property_id] => 80
[guest_allow] => 5
)
[6] => Array
(
[property_id] => 84
[guest_allow] => 3
)
)
So I have to match guest array all values are present in second array as well as I have to check guest values is less than to second array of guest_allow. If there is not match single value return empty array. If match value so return only match value. I want return array like this:
Array
(
[0] => Array
(
[property_id] => 6
[guest_allow] => 2
)
[1] => Array
(
[property_id] => 9
[guest_allow] => 3
)
[2] => Array
(
[property_id] => 62
[guest_allow] => 2
)
[3] => Array
(
[property_id] => 72
[guest_allow] => 3
)
[4] => Array
(
[property_id] => 84
[guest_allow] => 3
)
[5] => Array
(
[property_id] => 76
[guest_allow] => 4
)
)
Is it possible return this type array? Thanks.

Answer 1

Assuming that $guestArr is your guest array and $secondArr is your second array, the solution would be like this:
foreach($secondArr as $key => $arr){
if(!in_array($arr['guest_allow'], $guestArr)){
unset($secondArr[$key]);
}
}
// display $secondArr array
var_dump($secondArr);
Here's the live demo.

Answer 2

$first = [1, 2, 3];
$second = [
['property_id' => 6, 'guest_allow' => 2],
['property_id' => 66, 'guest_allow' => 3],
['property_id' => 76, 'guest_allow' => 4],
['property_id' => 86, 'guest_allow' => 2]
];
$result = array_filter($second, function($el) use ($first) {
return in_array($el['guest_allow'], $first);
});
