Sort array by key value without mysql

Question

How can I sort an array without the MYSQL order?

I have a key value called sort this is 1,2,3,0 etc. The array that I print is OK but I need to sort this array from low to high based on the sort value. How can I do this?

    foreach($res as $key=>$value){
        $res[$key]['subaddonsname'] = $this->getValue("addonsname",$CFG['table']['addons'],"id = '".$res[$key]['menuaddons_addonsname']."' ");
        $newArr[$key]['subaddonsort'] = $this->getValue("addonsort",$CFG['table']['addons'],"id = '".$res[$key]['menuaddons_addonsname']."' ");
    }

    echo "<pre>";print_r($res);echo "</pre>";exit();

this results

You could also do it like this

usort($res, function($a, $b) {
    if ($a['subaddonsort'] == $b['subaddonsort']) return 0;
    return $a['subaddonsort'] < $b['subaddonsort'] ? -1 : 1;
});

return $a['subaddonsort'] - $b['subaddonsort']; would also work.

PHP's sort functionality pretty much caters for all occasions.

Given the details of your question and PHP documentation, it seems you need to use asort() function:

asort($res);

die('<pre>' . print_r($res, true) . '</pre>');
