Refactoring smartrecruiter api - php

Question

I'm currently implementing smartrecruiter api in my project. I'm using two endpoints namely /jobs-list and /job-details. The problem is that every time I'm extracting the details in the second endpoint which is the /job-details, the execution time is so slow.
Here's what I've done so far:
function getContext()
{
$opts = array(
'http'=> array(
'method' => 'GET',
'header' => 'X-SmartToken: xxxxxxxxxxxxxxxxx'
)
);
return $context = stream_context_create($opts);
}
function getSmartRecruitmentJob($city, $department)
{
$tmp = array();
$results= array();
$limit = 100; //max limit for smartrecruiter api is 100
// Open the file using the HTTP headers set above
$file = file_get_contents('https://api.smartrecruiters.com/jobs?limit='.$limit.'&city='.$city.'&department='.$department, false, $this->getContext());
$lists= json_decode($file, true);
foreach($lists['content'] as $key => $list)
{
if ($list['status'] == 'SOURCING' || $list['status'] == 'INTERVIEW' || $list['status'] == 'OFFER')
{
$results['id'] = $list['id'];
$tmp[] = $this->getSmartRecruitmentJobDetails($results['id']);
}
}
return $tmp;
}
function getSmartRecruitmentJobDetails($id)
{
$results = array();
$file = file_get_contents('https://api.smartrecruiters.com/jobs/'.$id, false, $this->getContext());
$lists= json_decode($file, true);
$results['title'] = isset($lists['title']) ? $lists['title'] : null;
$results['department_label'] = isset($lists['department']['label']) ? $lists['department']['label'] : null;
$results['country_code'] = isset($lists['location']['countryCode']) ? $lists['location']['countryCode'] : null;
$results['city'] = isset($lists['location']['city']) ? $lists['location']['city'] : null;
$results['url'] = isset($lists['actions']['applyOnWeb']['url']) ? $lists['actions']['applyOnWeb']['url'] : null;
return $results;
}

Solved it by caching the function for extracting the data:
function getCache()
{
if ($this->cache === null)
{
$cache = \Zend\Cache\StorageFactory::factory(
array(
'adapter' => array(
'name' => 'filesystem',
'options' => array(
'ttl' => 3600 * 7, // 7 hours
'namespace' => 'some-namespace',
'cache_dir' => 'your/cache/directory'
),
),
'plugins' => array(
'clear_expired_by_factor' => array('clearing_factor' => 10),
),
)
);
$this->cache = $cache;
}
return $this->cache;
}
function getSmartRecruitmentJobDetails($id)
{
$cache = $this->getCache();
$key = md5('https://api.smartrecruiters.com/jobs/'.$id);
$lists = unserialize($cache->getItem($key, $success));
$results = array();
if($success && $lists)
{
header('Debug-cache-recruit: true');
}
else
{
header('Debug-cache-recruit: false');
// Open the file using the HTTP headers set above
$file = file_get_contents('https://api.smartrecruiters.com/jobs/'.$id, false, $this->getContext());
$lists= json_decode($file, true);
$cache->addItem($key, serialize($lists));
}
$results['title'] = isset($lists['title']) ? $lists['title'] : null;
$results['department_label'] = isset($lists['department']['label']) ? $lists['department']['label'] : null;
$results['country'] = isset($lists['location']['country']) ? $lists['location']['country'] : null;
$results['country_code'] = isset($lists['location']['countryCode']) ? $lists['location']['countryCode'] : null;
$results['city'] = isset($lists['location']['city']) ? $lists['location']['city'] : null;
$results['url'] = isset($lists['actions']['applyOnWeb']['url']) ? $lists['actions']['applyOnWeb']['url'] : null;
return $results;
}
