How can JSON decoding simplify the process of extracting specific values from a file in PHP?

When extracting specific values from a file in PHP, JSON decoding can simplify the process by converting the JSON data into a PHP array or object. This allows you to easily access and extract the specific values you need using array or object notation, rather than manually parsing the file data. 

// Read the JSON file contents
$jsonData = file_get_contents('data.json');

// Decode the JSON data into a PHP associative array
$data = json_decode($jsonData, true);

// Access and extract specific values from the array
$value = $data['key'];

// Alternatively, if the JSON data represents an object
// $data = json_decode($jsonData);

// Access and extract specific values from the object
// $value = $data->key;
