php - if array key is in another arrays value - php

Question

Sorry if this question is worded incorrectly or doesn't make any sense. What I am trying to do is write an if statement that checks if:
array(6) {
[5]=>
string(17) "Quality Assurance"
[6]=>
string(7) "Analyst"
[7]=>
string(19) "Developer/Front end"
[8]=>
string(18) "Developer/Back end"
[9]=>
string(4) "Test"
[10]=>
string(2) "hi"
}
Any of those keys, in this case, 5, 6, 7, 8, 9, 10 is in:
array(4) {
[0]=>
object(stdClass)#195 (2) {
["labour_type_id"]=>
int(5)
["required_labour_type_hours"]=>
int(40)
}
[1]=>
object(stdClass)#193 (2) {
["labour_type_id"]=>
int(6)
["required_labour_type_hours"]=>
int(80)
}
}
This second arrays "labour_type_id".
In this example, 5 and 6 would match.
I am trying to use the in_array() function but I am not sure how to access the labour_type_id of the second array.
My best attempt at the moment:
#foreach($labourTypes as $id => $name)
#if(in_array($id, $reqLabourTypes->labour_type_id))
Where labourTypes is the first array, and reqLabourTypes is the 2nd array.
Thanks.

I've cleaned up this little search for you to try and find it as you require:
$new = array_filter(array_map(function(&$item) use($requiredLabour, $labourTypes){
$key = array_search($item, $labourTypes);
foreach($requiredLabour as $elem){
if($elem['labour_type_id'] == $key) {
return array(
$key => $item,
'options' => $elem
);
}
}
}, $labourTypes));
Everything will be accessible in $new if found. It returns:
Array
(
[5] => Array
(
[5] => Quality Assurance
[options] => Array
(
[labour_type_id] => 5
[required_labour_hours] => 40
)
)
[6] => Array
(
[6] => Analyst
[options] => Array
(
[labour_type_id] => 6
[required_labour_hours] => 40
)
)
)
The above is just the output, you can change it to whatever you need it to be by simply editing the return array(..... inside to whatever you require.
