如何基于远程资源的类的一部分创建新数组

Question

I very new in php programing, and I have try to search on google and this stackoverflow for this solution but still not get it

I'm using the following code;

$url   = 'http://best1st.info/Moviedb/json.php?m=tt2015381&o=json';
$newdata = json_decode(file_get_contents($alsoKnownAs));

$alsoKnownAs = $data['ALSO_KNOWN_AS'];
echo "<pre>";
$newdata = json_decode(file_get_contents($alsoKnownAs));
echo "<pre>";
print_r($newdata);

I try to manipulate Array from IMDB data, if the array output like :

. and so on
.

[AWARDS] => 
[NOMINATIONS] => 
[VOTES] => 166,773
[LANGUAGE] => Array
    (
        [0] => English
    )

[COUNTRY] => Array
    (
        [0] => USA
        [1] => UK
    )

[STORYLINE] => On planet Earth in 1988, young Peter Quill ( ) sits in the waiting room of a hospital...
[ALSO_KNOWN_AS] => Array
    (
        [0] => Guardianes de la galaxia = Argentina
        [1] => Qalaktikanin Mühafizeçileri = Azerbaijan
        [2] => Пазителите на Галактиката = Bulgaria (Bulgarian title)
        [3] => Guardiões da Galáxia = Brazil
    )

[RELEASE_DATES] => Array
    (
        [0] => USA = 21 July 2014
        [1] => UK = 24 July 2014
        [2] => Canada = 29 July 2014
        [3] => Argentina = 31 July 2014
.
.
. and so on

How I create a New Array that just have "ALSO_KNOWN_AS" values?

Thanks you

Answer 1

Simple. As the data you require is already saved as an array you can retrieve it with;

$alsoKnownAs = $newdata->ALSO_KNOWN_AS;

So your code would look like this;

$url   = 'http://best1st.info/Moviedb/json.php?m=tt2015381&o=json';
$newdata = json_decode(file_get_contents($url));

$alsoKnownAs = $newdata->ALSO_KNOWN_AS;

You can then loop over the values with the following;

foreach($alsoKnownAs as $value) {
    echo '<pre>' . $value . '</pre><br>'; // to print each row of the data
    // $value is the value of each part of the array in turn, starting from 0
}
