You can do something like this: source for flatten from @too much php.

$arr=Array
 (
    '0' => Array
         (
             'title1' => '',
             'title2' => '',
             'image' => ''
         ),
    '1' => Array
         (
             'title1' => '',
             'title2' => '',
             'image' => ''
         ),
    '2' => Array
         (
             'title1' => 'SampleTitle',
             'title2' => '',
             'image' => ''
         )
);

function flatten(array $array) {
    $return = array();
    array_walk_recursive($array, function($a) use (&$return) { $return[] = $a; });
    return $return;
}

$str=flatten($arr);
if(!array_filter($str)) {
    echo "all are null";
}else{
    echo "values are there";
}
