What potential issues can arise when using file_get_contents with URLs containing special characters?

When using file_get_contents with URLs containing special characters, the URL needs to be properly encoded to ensure that the special characters are interpreted correctly. If the URL is not encoded, it can lead to errors or unexpected behavior when fetching the content. To solve this issue, you can use the urlencode function to encode the URL before passing it to file_get_contents. 

$url = "https://example.com/api/data?param1=value1&param2=value2";
$encoded_url = urlencode($url);
$content = file_get_contents($encoded_url);
echo $content;
