IMDB Api, retrieve title and plot only. - php

Question

I found this site, that provides IMDB API:
http://www.omdbapi.com
and for getting for example the hobbit's it's easy enough as this:
http://www.omdbapi.com/?i=tt0903624
Then I get all this information:
{"Title":"The Hobbit: An Unexpected Journey","Year":"2012","Rated":"11","Released":"14 Dec 2012","Runtime":"2 h 46 min","Genre":"Adventure, Fantasy","Director":"Peter Jackson","Writer":"Fran Walsh, Philippa Boyens","Actors":"Martin Freeman, Ian McKellen, Richard Armitage, Andy Serkis","Plot":"A curious Hobbit, Bilbo Baggins, journeys to the Lonely Mountain with a vigorous group of Dwarves to reclaim a treasure stolen from them by the dragon Smaug.","Poster":"http://ia.media-imdb.com/images/M/MV5BMTkzMTUwMDAyMl5BMl5BanBnXkFtZTcwMDIwMTQ1OA##._V1_SX300.jpg","imdbRating":"9.2","imdbVotes":"5,666","imdbID":"tt0903624","Response":"True"}
The thing is that I only want for exmaple the title, the year and the plot information, and I wonder how I can only retrieve this.
I want to use PHP.

Here you go... simply decode the json, and pull out the data you need. If need be, you can re-encode it as json afterwards.
$data = file_get_contents('http://www.omdbapi.com/?i=tt0903624');
$data = json_decode($data, true);
$data = array('Title' => $data['Title'], 'Plot' => $data['Plot']);
$data = json_encode($data);
print($data);
Another way to do this (slightly more efficiently) is to unset unneeded keys, e.g.:
$data = file_get_contents('http://www.omdbapi.com/?i=tt0903624');
$data = json_decode($data, true);
$keys = array_keys($data);
foreach ($keys as $key) {
if ($key != 'Title' && $key != 'Plot) {
unset($data[$key]);
}
}
$data = json_encode($data);
print($data);

OMDBAPI.com is no longer free to use. As you can read on their website:
05/08/17 - Going Private! Please go read the post on the Patreon page about this major change.
This means you must become a donator to get access to the API. I used their API for over a year and now it stopped. If you need to perform lots of queries then I think becoming a sponsor to OMDBAPI is a good idea. However I used their API in my little private project. After googling a bit I found another API. Here's the code you can use:
<?php
$imdbID = 'tt2866360';
$data = json_decode(file_get_contents('http://api.rest7.com/v1/movie_info.php?imdb=' . $imdbID));
if (#$data->success !== 1)
{
die('Failed');
}
echo '<pre>';
print_r($data->movies[0]);
I am not affiliated with this website. But I use this API so can answer a question or two if anyone has.
