What are the potential security risks when importing data from an API into a PHP application?

One potential security risk when importing data from an API into a PHP application is the possibility of injection attacks if the data is not properly sanitized. To mitigate this risk, it is essential to validate and sanitize the input data before using it in your application. This can be done by using functions like filter_var() or htmlentities() to filter out any potentially malicious content. 

// Example of sanitizing input data from an API before using it in a PHP application
$apiData = $_GET['api_data']; // Assuming this is the data retrieved from the API

// Sanitize the input data
$cleanData = filter_var($apiData, FILTER_SANITIZE_STRING);

// Now you can safely use $cleanData in your application
echo $cleanData;
