How can I get else value when compare key of array and value?

Question

output my first array

$arr_val

:

    Array

(

    [0] => 0

    [1] => 2

    [2] => 3

)

output second array

$pecah_arr

:

Array

(

    [0] => Kunyit dipercaya sebagai salah satu rempah yang dapat mendukung kesehatan hingga untuk pengobatan

    [1] => Sayangnya, pemakaian yang keliru justru berdampak sebaliknya

    [2] => Seperti berita yang diangkat NBC News, seorang wanita asal San Diego yang menerima pengobatan kunyit intravena harus mengakhiri nyawa.

    [3] => Jade Erick meninggal 16 Maret lalu setelah pergi ke India untuk melakukan pengobatan rempah-rempah untuk penyakit eksim yang dideritanya.

)

I want to get output like this,
if value in

$arr_val

same with key of

$pecah_arr

, print the value that same.
but if value in

$arr_val

not same with key of

$pecah_arr

, print the value that not same.

my logic like this:

    $hasil_ringkasan=array();

    foreach ($arr_val as $key => $value) {

        foreach ($pecah_arr as $key2 => $value2) {

            if($value==$key2){

                $no_doc=$value+1;

                array_push($hasil_ringkasan, $value2);

                //INSERT KE DB untuk Learning

                $q=$this->db->query("INSERT INTO tb_sementara 

                VALUES('$key2[$value]','$no_doc','$fitur1_uji[$value]','$fitur2_uji[$value]',

                    '$fitur3_uji[$value]','$fitur4_uji[$value]','$fitur5_uji[$value]','$fitur6_uji[$value]','ringkasan')");



                }else{

                // INSERT KE DB untuk Learning

                $q=$this->db->query("INSERT INTO tb_sementara 

                VALUES('$key2[$value]','$no_doc','$fitur1_uji[$value]','$fitur2_uji[$value]',

                    '$fitur3_uji[$value]','$fitur4_uji[$value]','$fitur5_uji[$value]','$fitur6_uji[$value]','bukan') 

                ");

            }



        }

    }

Although in

if

had worked, but I dont know why in

else

dont work.
thanks..

You do not need to iterate over $arr_val. Use in_array() instead.

$hasil_ringkasan=array();
    foreach ($pecah_arr as $key2 => $value2) {
        if(in_array($key2,$arr_val)){
            $no_doc=$value+1;
            array_push($hasil_ringkasan, $value2);
            //INSERT KE DB untuk Learning
            $q=$this->db->query("INSERT INTO tb_sementara 
            VALUES('$key2[$value]','$no_doc','$fitur1_uji[$value]','$fitur2_uji[$value]',
                '$fitur3_uji[$value]','$fitur4_uji[$value]','$fitur5_uji[$value]','$fitur6_uji[$value]','ringkasan')");

            }else{
            // INSERT KE DB untuk Learning
            $q=$this->db->query("INSERT INTO tb_sementara 
            VALUES('$key2[$value]','$no_doc','$fitur1_uji[$value]','$fitur2_uji[$value]',
                '$fitur3_uji[$value]','$fitur4_uji[$value]','$fitur5_uji[$value]','$fitur6_uji[$value]','bukan') 
            ");
        }


}
