What potential issues can arise when using the sendToHost function in PHP, particularly when sending GET requests with parameters?

When using the sendToHost function in PHP to send GET requests with parameters, potential issues can arise if the parameters are not properly encoded. This can lead to errors or unexpected behavior when the parameters contain special characters or spaces. To solve this issue, it is important to properly encode the parameters using urlencode() before appending them to the URL. 

// Encode the parameters before sending the request
$param1 = urlencode($param1);
$param2 = urlencode($param2);

// Build the URL with encoded parameters
$url = "http://example.com/api?param1=$param1&param2=$param2";

// Use sendToHost function to send the GET request
sendToHost($url);
