What I am wanting help is how can I loop over the array, so I get an output like this,

Employer Name

Job Title

Job Title

and then when the loop meets a new employer name, it outputs the employer name and their jobs?

---

(Sorry, I had missed your additional requirement.) Sort the array by employer name first:

function jobcmp($job1, $job2)
{
  return strcmp($job1['company_name'], $job2['company_name']);
}

uksort($jobarray, jobcmp);

Or even better, using a lambda:

uksort($jobarray, function($job1, $job2) { return strcmp($job1['company_name'], $job2['company_name']); });

Then use foreach:

$oldemp   = "";
foreach($jobarray as $key => $value)
{
   if ($oldemp != $value['company_name'])
   {
     $oldemp = $value['company_name'];
     print($oldemp);
   }

   print("Job Title: $value['job_title']");
}
