How can developers troubleshoot and resolve issues with CURL requests in PHP when encountering errors related to reserved characters in URLs?

When encountering errors related to reserved characters in URLs in CURL requests in PHP, developers can use the `urlencode()` function to encode the URL before making the request. This function will properly escape any reserved characters in the URL, ensuring that the request is sent correctly. 

$url = 'https://api.example.com/data?key=value with spaces';
$encoded_url = urlencode($url);

$ch = curl_init($encoded_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false){
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);
