Filter in .json file parameters

I created an .json file using the following code:

<?php
function get_data(){

$connect = mysqli_connect("localhost", "root", "", "videos");
$query = "SELECT * FROM 'tb_indice'";
$result = mysqli_query($connect, $query);
$data = array();
while($row = mysqli_fetch_array($result)){

    $data[] = array(
        'id'         => $row["id"],
        'titulo'     => $row["titulo"],
        'video'      => $row["video"],

    );
}
return json_encode($data);
}

$file_name = date('d-m-Y') . '.json';
if(file_put_contents($file_name, get_data())){
 echo $file_name . 'Arquivo criado';
} else {
 echo "Ocorreu algum erro na criação do arquivo .json";
} 

And I'm using:

$json = file_get_contents('http://localhost/01/20-01-2018.json');
$data = json_decode($json);

to return.

However I would like to search in the file (20-01-2018.json) parameters, example: link {title will be searched here)

link {here goes the searched id}
