Cum identific si scot din acest strig valori?

Salut

Am urmatorul cod:

<?php
$url = 'http://api..............................';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach($json['city']['list']['main'] as $item) {
	print $item['temp'];
}
?>

Si structura json:

{"city":{"id":683506,"name":"Bucharest","coord":{"lon":26.10626,"lat":44.432251},"country":"RO","population":0,"sys":{"population":0}},"cod":"200","message":0.0041,"cnt":40,"list":[{"dt":1459954800,"main":{"temp":301.7,"temp_min":299.019,"temp_max":301.7,"pressure":1016.43,"sea_level":1022.02,"grnd_level":1016.43,"humidity":50,"temp_kf":2.68},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02d"}],"clouds":{"all":24},"wind":{"speed":3.12,"deg":210},"sys":{"pod":"d"},"dt_txt":"2016-04-06 15:00:00"},{"dt":1459965600,"main":{"temp":295.65,"temp_min":293.119,"temp_max":295.65,"pressure":1017.22,"sea_level":1022.96,"grnd_level":1017.22,"humidity":60,"temp_kf":2.53},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02n"}],"clouds":{"all":24},"wind":{"speed":1.78,"deg":231.502},"sys":{"pod":"n"},"dt_txt":"2016-04-06 18:00:00"},{"dt":1459976400,"main":{"temp":291.1,"temp_min":288.722,"temp_max":291.1,"pressure":1017.51,"sea_level":1023.27,"grnd_level":1017.51,"humidity":70,"temp_kf":2.38},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02n"}],"clouds":{"all":20},"wind":{"speed":1.06,"deg":309.001},"sys":{"pod":"n"},"dt_txt":"2016-04-06 21:00:00"},........}

As dori sa pot scoate si afisa temp (nu temp_max sau temp_min) pentru prima valoare din lista.

Cum pot face acest lucru? Am tot incercat in fel si chip si nu am reusit (ce este in scriputl php este o varianta).

Multumesc

list nu-i in city, asa ca ramai cu $json['list']['main']

Multam pt raspuns.
Asa imi zice "Warning: Invalid argument supplied for foreach() in nume_fisier on line ...X".

Observ ca in list, este repetitive treaba cu {dt, main {},....}, si atunci ma gandeam sa fac si o indexare (ceva gen ['list]['main'][0] sau ['list']['main[0]']).
Mai "sap", mai "sap", dar orice sfat/idee e binevenita.

LE: gasisem si ma inspirasem de aici. Departe nu-s cred...

Gata, am reusit!

Solutia:

...
...
echo $json['list'][0]['main']['temp'];
...
...

PS. Se poate inchide! Multumesc
