PHP - Getting array element from Json - php

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;
}

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 />";
}
}
}
