Is it possible to use IP addresses instead of URLs in PHP functions like file() for better reliability?

When using PHP functions like file() with IP addresses instead of URLs, there may be issues with reliability due to potential DNS resolution problems. To solve this, you can use the IP address directly in the function call to ensure a more reliable connection. 

// Using IP address instead of URL in file() function
$file_contents = file('http://123.456.789.10/file.txt');
foreach ($file_contents as $line) {
    echo $line;
}
