Question

Sorry, it might be a very simple answer, but I have tried and took a look at google several times and I am disparing right now. I want to clear the following array ($list). Here is a print_r:

Array ( [0] => Array ( 
           [0] => 1 
           [1] => Tomato 
           [2] =>
        ) 
        [1] => Array ( 
           [0] => 
        ) 
      ) 

I want to get rid of [2] => after Tomato and the second value [1] => Array ( [0] => ) There might be ten or more worts like Tomato.

Thanks!

Example from comments below array_filter documentation:

function array_filter_recursive($array, $callback = null) {
    foreach ($array as $key => & $value) {
        if (is_array($value)) {
            $value = array_filter_recursive($value, $callback);
        }
        else {
            if ( ! is_null($callback)) {
                if ( ! $callback($value)) {
                    unset($array[$key]);
                }
            }
            else {
                if ( ! (bool) $value) {
                    unset($array[$key]);
                }
            }
        }
    }
    unset($value);

    return $array;
}
