In PHP, what considerations should be made when dealing with exported data from external tools that may not adhere to standard formatting or include unexpected characters?

When dealing with exported data from external tools that may not adhere to standard formatting or include unexpected characters, it is important to sanitize the data to prevent any potential security vulnerabilities or parsing errors. One way to address this is by using PHP's `filter_var` function with the `FILTER_SANITIZE_STRING` flag to remove any unwanted characters or formatting from the data. 

$exportedData = $_POST['exported_data']; // Assuming the exported data is received via POST request

// Sanitize the exported data
$sanitizedData = filter_var($exportedData, FILTER_SANITIZE_STRING);

// Now you can safely use the sanitized data in your application
// For example, you can store it in a database or display it on a webpage
