Find all objects with same property in array PHP - php

Question

I am having a bit of difficulty testing one array against another.
I have a persons array
0 =>
object(Prospect)[196]
private 'firstname' => string 'Jane'
private 'surname' => string 'Doe'
private 'email' => string 'test#test.com'
private 'postcode' => string 'LS'
public 'region' => string 'Yorkshire'
1 =>
object(Prospect)[197]
private 'firstname' => string 'John'
private 'surname' => string 'Doe'
private 'email' => string 'test1#test.com'
private 'postcode' => string 'CH'
public 'region' => string 'Cheshire'
and a jobs array
0 =>
object(Job)[2]
private 'title' => string 'Job 1'
private 'ref' => string '0001'
private 'postcode' => string 'CH'
public 'region' => string 'Cheshire'
private 'wage' => string '£250'
1 =>
object(Job)[3]
private 'title' => string 'Job 2'
private 'ref' => string '0002'
private 'postcode' => string 'CH'
public 'region' => string 'Cheshire'
private 'wage' => string '£200.00'
What is the best way to iterate over each person in the persons array to find all jobs in the jobs array that have the same region for that particular person?
Edit: The data that I am working with is large on the prospect side and the job side, the above is just an example of the data that I am working with.
My overall goal for this is to be able to link each prospect with up to 6 jobs in the same region and then output this data into CSV file(s) to be used in a third party email campaign service.
I am quite new to this so would be grateful of any help
Thanks

Answer 1

Try this:
$persons_region = 'Cheshire';
$found_jobs = array();
foreach ($jobs as $job) {
if ($job['region'] == $persons_region) {
$found_jobs[] = $job;
}
}

Answer 2

the simpliest but maybe slowest way is
$job_ids = array();
foreach($persons_array as $person) {
foreach ($jobs_array as $id=>$job) {
if ($person->region == $job->region) $job_ids[] = $id;
}
}
so you can do
foreach ($job_ids as $id) {
// whatever using $id
}
