Pull data from nested json loop php - php

Question

Ok, I have been fighting this for two days now!! Here is my Json structure.
[
{
"uuid":"/random number==",
"meeting_number":7196503037,
"host_id":"random number",
"topic":"My's Personal Meeting Room",
"start_time":"2015-01-06T22:01:07Z",
"timezone":"America/Denver",
"duration":56,
"total_size":378080,
"recording_count":1,
"recording_files":[
{
"id":"long number",
"meeting_id":"/NS90bsSTLeGzo6cT0nwXw==",
"recording_start":"2015-01-06T22:01:09Z",
"recording_end":"2015-01-06T22:01:14Z",
"file_size":378080,
"play_url":"https://myurl"
}
]
},
I am trying to pull the Start Time from the top level array (which is named 'meetings') and the Play Url from the second level array (recording_files). I am using json_decode to decode the file into arrays.
I have tried many variations found on this site and nothing seems to get to the play url.
VARIATION 1
$aha = json_decode($response,true);
foreach ($aha['meetings'] as $key => $value){
foreach($key['recording_files'] as $subkey => $newvalue){
echo '<p>Time : '.$value['start_time'].'</p>
Recording<br>';
}}
This pulls an invalid argument in foreach.
VARIATION 2
foreach ($aha['meetings'] as $key => $value){
echo '<p>Time : '.$value['start_time'].'</p>
Recording<br>';
}
This pulls undefined index for play_url. As does the same code with the reference to ['recording_files'] placed before ['play_url']
VARIATION 3:
Then I tried giving up on the first level and just pulling data from the second level:
$aha = json_decode($response,true);
foreach ($aha['meetings']['recording_files'] as $key => $value){
echo '<p>Time : '.$value['recording_start'].'</p>
Recording<br>';
}
That gives me an undefined index on ['recording_files'] and a foreach error.
VARIATION 4.
$aha = json_decode($response,true);
foreach ($aha['meetings'] as $key => $value){
$link=$key['recording_files'];
echo '<p>Time : '.$value['start_time'].'</p>
Recording<br>';
}
This gets me the closest - no errors but no link. I presume that here the code is seeing the field but just not pulling the data from it...
Please help a newbie json person!!

Answer 1

If there is really an $aha['meetings'] (you don't show it), then use the value not the key in the second foreach:
foreach($aha['meetings'] as $value){
foreach($value['recording_files'] as $newvalue){

Answer 2

Final code that fixed it.
$aha = json_decode($response,true);
foreach ($aha['meetings'] as $key => $value){
echo '<p>Time : '.$value['start_time'].'</p>
Recording<br>';}
It was just a matter of finding the correct format for referencing the play_url piece.
Thank you so much to everyone!

Edit:
If your data looks like this :
$str = "{\"meetings\":[{
\"uuid\":\"/random number==\",
\"meeting_number\":7196503037,
\"host_id\":\"random number\",
\"topic\":\"My's Personal Meeting Room\",
\"start_time\":\"2015-01-06T22:01:07Z\",
\"timezone\":\"America/Denver\",
\"duration\":56,
\"total_size\":378080,
\"recording_count\":1,
\"recording_files\":[
{
\"id\":\"long number\",
\"meeting_id\":\"/NS90bsSTLeGzo6cT0nwXw==\",
\"recording_start\":\"2015-01-06T22:01:09Z\",
\"recording_end\":\"2015-01-06T22:01:14Z\",
\"file_size\":378080,
\"play_url\":\"https://myurl\"
}
]
}]}";
$json = json_decode($str);
$res = $json->{'meetings'};
foreach($res as $keys){
echo $keys->{'start_time'}."<br>";
foreach ($keys->{'recording_files'} as $data){
echo $data->{'play_url'}."<br>";
echo $data->{'recording_start'}."<br>";
}
}
