What are common issues when using json_decode in PHP with different server configurations?

One common issue when using `json_decode` in PHP with different server configurations is that the function may not work as expected if the JSON data is not valid. To solve this issue, you can add error handling by checking if the JSON data is valid before decoding it. 

$json_data = '{"key": "value"}';

// Check if JSON data is valid
if (json_decode($json_data) === null && json_last_error() !== JSON_ERROR_NONE) {
    die("Invalid JSON data");
}

// Decode JSON data
$data = json_decode($json_data);

// Use the decoded data
var_dump($data);
