What is the potential risk of using eval() to parse PHP code in a string?

Using eval() to parse PHP code in a string can pose a security risk as it allows for the execution of arbitrary code, making the application vulnerable to code injection attacks. To mitigate this risk, it is recommended to avoid using eval() whenever possible and instead use alternative methods such as built-in PHP functions like json_decode() or regular expressions to parse the code. 

// Fix: Avoid using eval() to parse PHP code in a string
// Example using json_decode() to parse JSON data

$jsonData = '{"name": "John", "age": 30}';
$parsedData = json_decode($jsonData);

echo $parsedData->name; // Output: John
echo $parsedData->age; // Output: 30
