one action per array value

[mjsmitten]

The program I use takes items out of a database per query.

<?php myquery(array('region'=>'florida','region'=>'florida','region'=>'florida'));?>

I have regions per example (florida, georgia, delaware, etc.).
After the query it return: more items from one state then the other; nothing; or just one (depending on what users are posting).

Now I would only like to show one (if present) from each state.

I was thing something like this: if (in_array('' '') do this...
But do not know if this is the right function and how to use it.

I think it would be easier to adjust your query to return what you want. If you show the query you are using now, we can suggest changes to it.

Maybe it's possible to walk through the array, every key one time?
now I use <?php osc_query_item(array('region'=>'florida','region'=>'georgia','region'=>'delaware'));?>
after the query gets all values that belong to an item, such as region, in which i am interested.
I need to walk through the value from region and only do one action, then go to the next region, etc.

function osc_query_item($params = null) {
    $mSearch = Search::newInstance();
    if($params==null) {
        $params = array();
    } else if(is_string($params)){
        $keyvalue = explode("=", $params);
        $params = array($keyvalue[0] => $keyvalue[1]);
    }
    foreach($params as $key => $value) {
        switch($key) {
            case 'author':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->fromUser($t);
                }
                break;

            case 'category':
            case 'category_name':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->addCategory($t);
                }
                break;

            case 'country':
            case 'country_name':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->addCountry($t);
                }
                break;

            case 'region':
            case 'region_name':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->addRegion($t);
                }
                break;

            case 'city':
            case 'city_name':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->addCity($t);
                }
                break;

            case 'city_area':
            case 'city_area_name':
                $tmp = explode(",", $value);
                foreach($tmp as $t) {
                    $mSearch->addCityArea($t);
                }

            case 'results_per_page':
                $mSearch->set_rpp($value);
                break;

            case 'page':
                $mSearch->page($value);
                break;

            case 'offset':
                $mSearch->limit($value);
                break;

            default:
                osc_run_hook('custom_query', $key, $value);
                break;
        }
    }
    View::newInstance()->_exportVariableToView("customItems", $mSearch->doSearch());
}
