Check if a specific value exists at a specific key in any subarray of a multidimensional array

Question

I need to search a multidimensional array for a specific value in any of the indexed subarrays.

In other words, I need to check a single column of the multidimension

Answer 1

function checkMultiArrayValue($array) {
        global $test;
        foreach ($array as $key => $item) {

            if(!empty($item) && is_array($item)) {
                checkMultiArrayValue($item);
            }else {
                if($item)
                 $test[$key] = $item;

            }
        }
        return $test;   
    }

 $multiArray = array(    
                0 =>  array(  
                      "country"   => "",  
                      "price"    => 4,  
                      "discount-price" => 0,  
               ),);

$test = checkMultiArrayValue($multiArray);
echo "
"
print_r($test);


Will return array who have index and value
