Afficher des données API en PHP

Bonjour,
Moi c'est Ludovic j'ai 28 ans.
Débutant en PHP, j'essaie de m'intéresser à la manipulation d'API.
J'essaie d'afficher les données d'une API mais ... je n'y arrive pas (évidemment)
Je viens évidemment sur le forum pour avoir de l'aide (évidemment avant j'ai essayé de parcourir les sites pour essayer de trouver des infos pour me dépatouiller).

J'ai construit mon code de la façon suivante :
J'ai mis un script cURL en début de fichier (script qui fonctionne puisque j'ai bien les datas brutes de l'API qui s'affichent avec l'echo du $response. Mon problème c'est pour les afficher)
Voici les données affichées par le $response

Mon script curl en entête

<?php
$curl = curl_init();

curl_setopt_array($curl, [
    CURLOPT_URL => "https://url de mon api/",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
    echo "cURL Error #:" . $err;
} else {
    echo $response."<br />";
}
?>

Ensuite j'ai fait la construction de ma page (avec le squelette HTML classique) et dans le body j'ai fait le test sur le genre_ids avec un script pour essayer d'afficher des données

<?php
    $resultat = json_decode($response,true);
        foreach($resultat as $film) {
            $id_genre = $film->results->genre_ids;
            echo $id_genre;
               }
?>

Donc j'ai des messages d'erreur disant
Warning: Attempt to read property "results" on int in [l'adresse de mon site] online 38
Warning: Attempt to read property "genre_ids" on null in [l'adresse de mon site] online 38
Warning: Attempt to read property "results" on array in [l'adresse de mon site] online 38

J'ai dû coder comme un goret (ne sachant pas comment faire, j'ai tâtonné à droite à gauche pour essayer d'obtenir des infos et j'ai dû me perdre)

Merci pour l'attention et l'aide que vous me donnerez
Ludo

Hello,

Le deuxième argument (positionné à true) que tu passes à json_decode permet d'indiquer à la fonction de renvoyer les données sous la forme d'un tableau associatif et non d'un objet.

Pour accéder aux différents éléments des données la bonne syntaxe est donc :

<?php
    $resultat = json_decode($response,true);
    foreach($resultat as $film) {
        $id_genre = $film['results']['genre_ids'];
        echo $id_genre;
    }
?>

Voir la documentation de la fonction json_decode : https://www.php.net/manual/en/function.json-decode.php

Merci je vais essayer
