Get JSON from URL by PHP - php

Question

I have a URL that returns a JSON object like this:
[
{
"idIMDB": "tt0111161",
"ranking": 1,
"rating": "9.2",
"title": "The Shawshank Redemption",
"urlPoster": "http:\/\/ia.media-imdb.com\/images\/M\/MV5BODU4MjU4NjIwNl5BMl5BanBnXkFtZTgwMDU2MjEyMDE#._V1_UX34_CR0,0,34,50_AL_.jpg",
"year": "1994"
}
]
URL : http://www.myapifilms.com/imdb/top
I want to get all of the urlPoster value and set in a array's element, and convert array to JSON so echo it.
How can I do it through PHP?

Answer 1

You can do something like that :
<?php
$json_url = "http://www.myapifilms.com/imdb/top";
$json = file_get_contents($json_url);
$data = json_decode($json, TRUE);
echo "<pre>";
print_r($data);
echo "</pre>";
?>

Answer 2

$json = file_get_contents('http://www.myapifilms.com/imdb/top');
$array = json_decode($json);
$urlPoster=array();
foreach ($array as $value) {
$urlPoster[]=$value->urlPoster;
}
print_r($urlPoster);

Answer 3

You can simply decode the json and then pick whatever you need:
<?php
$input = '[
{
"idIMDB": "tt0111161",
"ranking": 1,
"rating": "9.2",
"title": "The Shawshank Redemption",
"urlPoster": "http:\/\/ia.media-imdb.com\/images\/M\/MV5BODU4MjU4NjIwNl5BMl5BanBnXkFtZTgwMDU2MjEyMDE#._V1_UX34_CR0,0,34,50_AL_.jpg",
"year": "1994"
}
]';
$content = json_decode($input);
$urlPoster = $content[0]->urlPoster;
echo $urlPoster;
The output obviously is the URL stored in that property:
http://ia.media-imdb.com/images/M/MV5BODU4MjU4NjIwNl5BMl5BanBnXkFtZTgwMDU2MjEyMDE#._V1_UX34_CR0,0,34,50_AL_.jpg
BTW: "The Shawshank Redemption" is one of the best films ever made...

Answer 4

This how you do the same thing with array_map function.
<?php
#function to process the input
function process_input($data)
{
return $data->urlPoster;
}
#input url
$url = 'http://www.myapifilms.com/imdb/top';
#get the data
$json = file_get_contents($url);
#convert to php array
$php_array = json_decode($json);
#process the data and get output
$output = array_map("process_input", $php_array);
#convert the output to json array and print it
echo json_encode($output);
