I have a JSON feed and within the feed, there is an array inside the feed, I can output everything above the array correctly.
JSON feed output: http://pastebin.com/pxiFVm1d
Code used to output:
$jsonurl = "LINK to feed";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);
foreach ( $json_output->results as $results )
{
echo "{$results->name}.<br />";
}
How do I output the photo_rerence which is part of the array (see pastebin)?
If there's the possibility that there might be multiple photos you could do:
$json_output = json_decode($json);
foreach ( $json_output->results as $results )
{
foreach($results->photos as $photo) {
echo $photo->photo_reference;
}
}
Or if you only ever want to grab from the first one in the array just do:
$json_output = json_decode($json);
foreach ( $json_output->results as $results )
{
echo $results->photos[0]->photo_reference;
}
Either you make a "deep pick": $results['photos']['photo_reference'], or take a look at phps array_walk() function which allows you to "search" through the array in a recursive manner.
Just to add to what arkascha said, if you want to use it as an array, you will need to add the second param on your json_decode:
$json_output = json_decode($json, TRUE);
Refer to php.net/json_decode for details.
