How can the use of json_decode in PHP be more effective for handling and manipulating data compared to manually parsing strings?

When handling JSON data in PHP, using the json_decode function is more effective than manually parsing strings because it automatically converts JSON data into a PHP array or object, making it easier to access and manipulate the data. This eliminates the need to write complex string manipulation code and reduces the chances of errors. Additionally, json_decode handles various data types and structures in JSON data more efficiently.

// Example code using json_decode to handle JSON data
$jsonData = '{"name": "John", "age": 30, "city": "New York"}';
$data = json_decode($jsonData);

// Accessing and manipulating the data
echo $data->name; // Output: John
$data->age = 31;
$newJsonData = json_encode($data);
echo $newJsonData; // Output: {"name":"John","age":31,"city":"New York"}
