What could be causing the error "php_network_getaddresses: gethostbyname failed" when using file() function in PHP?

The error "php_network_getaddresses: gethostbyname failed" typically occurs when the file() function in PHP is unable to resolve the hostname of the URL being passed to it. This could be due to a DNS resolution issue or an incorrect URL format. To solve this issue, ensure that the URL being passed to the file() function is valid and that the server has proper DNS resolution capabilities. 

$url = 'https://www.example.com/file.txt';
$file_contents = file($url);
if($file_contents !== false) {
    foreach($file_contents as $line) {
        echo $line;
    }
} else {
    echo "Error fetching file.";
}
