What are the potential reasons for getting a blank page instead of an error or false return when using file_get_contents in PHP?

When using file_get_contents in PHP, a blank page could be returned instead of an error or false due to various reasons such as the file not existing, incorrect file permissions, or an issue with the server configuration. To solve this issue, you can check if the file_get_contents function returns false and handle the error accordingly by displaying a message to the user or logging the error for debugging. 

$url = 'example.txt';

$content = file_get_contents($url);

if($content === false){
    echo 'Error: Unable to retrieve file content';
} else {
    echo $content;
}
