Accessing JSON Data in PHP: Extracting Temperature Data

This PHP problem aims to extract specific data, namely "temperatureMin" and "temperatureMax," from a JSON file. To achieve this, we'll leverage the file_get_contents() function to retrieve the file's content.

Next, we'll utilize json_decode() to convert the JSON string into an associative array. This array will contain the desired data, which can be accessed using the following approach:

$str = file_get_contents('file.json');
$json = json_decode($str, true); // decode JSON into associative array

$temperatureMin = $json['daily']['data'][0]['temperatureMin'];
$temperatureMax = $json['daily']['data'][0]['temperatureMax'];

Alternatively, you can iterate through the array using a foreach loop:

foreach ($json['daily']['data'] as $field => $value) {
    // Access field and value here
}

This approach provides a comprehensive method for accessing and extracting specific data from a JSON file in PHP.
