Answer 1

Try this to find the parent index

$Arr = [
        [
          "title" => ["news", "nasional", "internasional", "regional", "metropolitan", "sains", "pendidikan"],
          "url" => "AAA",
       ],
       [
         "title" => ["seleb", "news"],
         "url" => "BBB"
       ],
       [
         "title" => "travel",
         "url" => "CCC"
       ]
      ];

   foreach($Arr as $key => $value) {
     if(is_array($value['title'])){
        if(in_array("seleb", $value['title']))
           echo $key;
     }
   }
