PHP - Getting array element from Json

Question

I'm working with the JSON here: http://steamcommunity.com/id/mitch8910/inventory/json/730/2/

I'm trying to get the tags[{"name":""}] part of it. For example, I would want the 'container', from '"name":"Container"'

This is my code here:

 $data = file_get_contents('http://steamcommunity.com/id/mitch8910/inventory/json/730/2/');
 $json = json_decode($data);
 foreach ($json->rgDescriptions as $mydata)
 {
 echo $mydata->tags[1];
 }

tags[] is an array, though I did tags[1], I don't awlays want the '1'th element because the position of "name" could change in the array for different elements, I just did this to test, but I got an error. I have tried multiple ways with multiple errors, that why I'm not posting all the error code.

Answer 1

The simplest way may be to do an extra loop to grab all the name elements:

$data = file_get_contents('http://steamcommunity.com/id/mitch8910/inventory/json/730/2/');
$json = json_decode($data);
foreach ($json->rgDescriptions as $mydata)
{
 foreach($mydata->tags as $tag) {
 echo $tag->name;
 }
}

or to get the first name of each tag group:

foreach ($json->rgDescriptions as $mydata)
{
 echo $mydata->tags[0]->name;
}

• MitchCool1: Thanks, that works. Though, in each of the tag[] arrays, there are a few groups in curly brackets {} and each group has a "name" element in it. Do you think it would be possible to just get the "name" from the first set of curly brackets?
• John C: $mydata->tags[0]->name; will just get the first one, without needing the second loop

Answer 2

I updated the whole answer:

$json = json_decode($data, true);
if (isset($json['rgDescriptions']) && is_array($json['rgDescriptions'])){
 foreach ($json['rgDescriptions'] as $array_no => $value) {
 if (isset($json['rgDescriptions'][$array_no]['tags'])){
 echo "{$array_no}::::";
 foreach ($json['rgDescriptions'][$array_no]['tags'] as $k => $value) {
 if (isset($json['rgDescriptions'][$array_no]['tags'][$k]['name'])){
 echo "{$json['rgDescriptions'][$array_no]['tags'][$k]['name']},";
 }
 }
 echo "<br />";
 }
 }
}

• MitchCool1: What does this do? All it seems to do is no longer allow me to go through the elements with my foreach, which I need to do, and I still can't get the "name" element.
• besciualex: I updated the answer. Now it checks if rgDescriptions is set and is an array. If yes it goes deeper through each contained array, and check if it has [name] tag inside the second row of arrays. If it is, then it prints it.
• MitchCool1: Thanks, this did work properly. Though I just need the first 'name' element in the tags array because there were a few for each item. I'm sure you could have done this, John C just gave me an answer on how to do that though.
