apparemment mon résultat correspond donc aux 48 prochaines heures
comment je pourrais faire pour lui indiquer les heures pour chaque prévision

ah d accord désolé
lorsque j' exécute ce code
voici ce que j obtiens en retour

2021-04-17 17:00:00
2021-04-17 18:00:00

ce n'est pas à mettre dans une boucle, juste savoir à quoi correspond le champ dt

bonjour or 1

merci pour la réponse et l aide

voici la boucle que j utilise pour avoir ce résultat

[code] $raw = file_get_contents($url);
$json = json_decode($raw);
foreach ($json->hourly as $hourly) {
$hourly>dt; // le timestamp du jour, tu as aussi sunrise, sunset, etc
$hourly->temp; // les températures avec $daily->temp->day; $daily->temp->max; etc
$hourly->weather; // la météo avec $daily->weather[0]->main; $daily->weather[0]->description; etc
print_r($hourly->weather) ;
echo "<br>";[/code]

je place donc a quel endroit le morceau de code que tu m as donne stp

echo date('Y-m-d H:i:s', 1618678800)."<br />";
echo date('Y-m-d H:i:s', 1618682400);

pour les id :
https://openweathermap.org/weather-conditions#Weather-Condition-Codes-2
[PHP]
echo date('Y-m-d H:i:s', 1618678800)."<br />";
echo date('Y-m-d H:i:s', 1618682400);
[/PHP]
"Time of the forecasted data, Unix, UTC", il y a donc un ajustement à faire pour avoir l'heure dans notre fuseau horaire.

bonjour a tous

grâce a vous je parviens a maitriser la météo pour les jours

a présent je me pence un peu sur "hourly"
je pensais que cela était les heures , mais en fait ce sont des périodes

grâce a mon lien je parviens donc a afficher uniquement les jours et le fameux "hourly"
mais j ai du mal a comprendre a quel période il correspond et aussi a quoi servent les id
