Delete element from multidimensional-array based on value

Solution 1:

Try this:

function removeElementWithValue($array, $key, $value){
     foreach($array as $subKey => $subArray){
          if($subArray[$key] == $value){
               unset($array[$subKey]);
          }
     }
     return $array;
}

Then you would call it like this:

$array = removeElementWithValue($array, "year", 2011);

Solution 2:

Try this:

function remove_element_by_value($arr, $val) {
   $return = array(); 
   foreach($arr as $k => $v) {
      if(is_array($v)) {
         $return[$k] = remove_element_by_value($v, $val); //recursion
         continue;
      }
      if($v == $val) continue;
      $return[$k] = $v;
   }
   return $return;
}

Solution 3:

$array[] = array('year' => 2010, "genres_text" => "Drama / Komedie");
$array[] = array('year' => 2011, "genres_text" => "Actie / Thriller");
$array[] = array('year' => "2010", "genres_text" => "Drama / Komedie");
$array[] = array('year' => 2011, "genres_text" => "Romance");

print_r(remove_elm($array, "year", 2010)); // removes the first sub-array only
print_r(remove_elm($array, "year", 201)); // will not remove anything
print_r(remove_elm($array, "genres_text", "drama", TRUE)); // removes all Drama
print_r(remove_elm($array, "year", 2011, TRUE)); // removes all 2011

function remove_elm($arr, $key, $val, $within = FALSE) {
    foreach ($arr as $i => $array)
            if ($within && stripos($array[$key], $val) !== FALSE && (gettype($val) === gettype($array[$key])))
                unset($arr[$i]);
            elseif ($array[$key] === $val)
                unset($arr[$i]);

    return array_values($arr);
}
