Pagina php con tabella con dati da json

20 mag 2023, 19:28

Buongiorno,

premetto che sono abbastanza ignorante in materia, mi servirebbe una pagina php che mi metta in tabella i dati forniti da questo json

Qui non si sviluppano software su commissione, pertanto se è vero che hai bisogno di aiuto, posta il codice che hai scritto e spiega gli errori che ottieni con la tua prova.

Premesso che Alka ha perfettamente ragione e probabilmente l'utente ha già trovato “aiuto” altrove, per non lasciare il thread senza risposta visto che l'argomento è interessante per gli alunni che si apprestano ad affrontare l'esame di stato di informatica, propongo un frammento di codice che non è risolutivo ma da un possibile indirizzo, se i moderatori non mi bacchettano anche questa volta.
La soluzione è semplice:
- si apre/legge il file json da opportuno path dove vengono generati/depositati
- si decodifica con le funzioni php o in un array associativo o in un oggetto
- si procede alla visualizzazione nel modo preferito
```
<?php

$percorso_file = 'test.json';
$json2string = file_get_contents($percorso_file);
//$dati = json_decode($json2string, true); //restituisce un vettore
$dati = json_decode($json2string, false);  //restituisce un oggetto

echo "Latitudine: ".$dati->latitude;
echo "<br>";
echo "Longitudine: ".$dati->longitude;
//...
```
Diciamo che JSON in genere è più facile vederlo interagire con JS, e la stessa visualizzazione proposta non tiene conto di un modello MVC dignitoso.
un pezzo del JSON proposto
```
{
    "latitude":45.82,
    "longitude":11.779999,
    "generationtime_ms":0.8679628372192383,
    "utc_offset_seconds":7200,
    "timezone":"Europe/Berlin",
    "timezone_abbreviation":"CEST",
    "elevation":191.0,
    "current_weather":
    ...
```
