Question

I have a PHP key/value array and I want to grab a value from there and display it in a div.

So far I have:

$homepage = file_get_contents('http://graph.facebook.com/1389887261/reviews');
$parsed = json_decode($homepage);

I want to get the values out of the key/value pair array like this:

foreach ($parsed as $key => $values){
    echo $values['rating'];
}

But this does not retrieve the value. What am I doing wrong?

Answer 1

Use the PHP foreach index reference, this gives you the ability to grab the key or the value.

$parsed = json_decode($homepage,true);
foreach ($parsed['data'] as $key => $values){
    echo $values['rating'];
}
