how to connect ombd api using php script

i have created a search option for a site to get movie details using mysql database BUT i want to connect them using the omdb api but i cant figure out please help me with this

this is my db connection using mysql database

<?php

//variables
$server = "localhost";
$username = "root";
$password = "";
$dbname = "devsearch";


$conn = mysqli_connect($server, $username, $password, $dbname);

OMDb API: http://www.omdbapi.com/?i=tt3896198&apikey=[MY_API_KEY]

If your question is about how to retrieve information from the Open Movie Database, with a PHP script, you can use this PHP code:

function getImdbRecord($ImdbId, $ApiKey)
{
    $path = "http://www.omdbapi.com/?i=$ImdbId&apikey=$ApiKey";
    $json = file_get_contents($path);
    return json_decode($json, TRUE);
}

$data = getImdbRecord("tt3896198", "f3d054e8");

echo "<pre>";
print_r($data);
echo "</pre>";

Please read the tip in the PHP manual about fopen wrappers if you have trouble reading from an URL.

The code above will return this result:
