Try

foreach($input as $key1=>$level1) {
    if(is_array($level1)) {
        foreach($level1 as $key2=>$level2) {
            if(is_array($level2)) {
                foreach($level2 as $key3=>$level3) {
                    if(is_array($level3)) {
                        foreach($level3 as $key4=>$level4) {
                            if(isset($level4)) {
                                $output[$key1][$key2][$key3][$key4]=$level4;
                            }
                        }
                    }
                    else {
                        if(isset($level3)) {
                            $output[$key1][$key2][$key3]=$level3;
                        }
                    }
                }
            }
            else {
                if(isset($level2)) {
                    $output[$key1][$key2]=$level2;
                }
            }
        }
    }
    else {
        if(isset($level1)) {
            $output[$key1]=$level1;

use foreach function and loop through the array and using the $key in the foreach check if($key=='testid') {//populate} if($key=='ESR') and like wise. You need to do it in seperate foreach for the coding comfort.
