Why does my foreach take forever to load

Question

This piece of code is run when i hit the submit button on my site to filter out results by address. But for some reason it takes forever for the page to reload, if anyone has any ideas how i can optimize my code please let me know.

I added 2 functions below that should explain what they do better.

Thanks in advance.

  $location = !empty($_POST['saddress']) ? $_POST['saddress'] : "NA";

if ($location != "NA")
    $display = true;
$street = explode(',', $location);
$users = get_users('orderby=nicename&role=employer');
global $wpdb;

$location = $_POST['saddress'];

$street = explode(',', $location);
$cat = $_GET['specializingin'];
//$specilty = 'specialties_'. $cat;


$args = array(
    'meta_query' => array(
        array(
            'key' => 'scategory',
            'value' => $_GET['specializingin'],
            'compare' => 'LIKE'
        ),
        array(
            'key' => 'specialties',
            'value' => ($_GET['specialitiesin'] == 'All Specialties' ? '' : $_GET['specialitiesin']),
            'compare' => 'LIKE'
        ),
    ),
);
//p($args);
$search_users = get_users($args);
//p($search_users);
$formattedAddress = prettyAddress($location);

foreach ($search_users as $k => $user):
    if (!empty($street[0])) {
        $db = prettyAddress(get_user_meta($user->ID, 'company_address', true));
        $match = matchAddress($formattedAddress, $db, count($street));
        if ($match == false)
            unset($search_users[$k]);
    }
endforeach;


$search_users = custom_sorting($search_users);

All of code:

Answer 1

I ended up creating a cron job to fetch the data from the API, store the results in multiple text files and then fetch the data from the text files which is much faster than querying the API multiple times.

query geocode api daily cron job setup

add_action('geocode_daily_event', 'geocode_daily');

function geocode_activation() {
    if ( !wp_next_scheduled( 'geocode_daily_event' ) ) {
        wp_schedule_event( current_time( 'timestamp' ), 'twenty_two_hours', 'geocode_daily_event');
    }
}
add_action('wp', 'geocode_activation');
function geocode_daily(){
    $args = array(
        'meta_query' => array(
            array(
                'key' => 'company_address'
            ),
        ),
    );

    //query execution
    $search_companies = get_users($args);

    foreach ($search_companies as $user){
        $address =  get_user_meta($user->ID, 'company_address', true);
        $address = str_replace(" ", "+", $address);

        $url = "https://maps.googleapis.com/maps/api/geocode/json?address=$address&key={YOUR GEOCODE API KEY HERE}";

        $cache_path = get_stylesheet_directory().'/geocode-cache/';
        $filename = $cache_path.md5($url);

        $result  = file_get_contents($url);
        file_put_contents($filename, $result );
    }
