Description:
------------
I try to read an export of a Google Sheet with file_get_contents.
With PHP 8, the first line of the export "is removed".

Test script:
---------------
error_reporting(E_ALL);
ini_set('display_errors', 1);

$data = file_get_contents('https://docs.google.com/spreadsheets/d/e/2PACX-1vTqS3j4Wd-Bt7Zb52eJiQed_NilvKo0wGdw8noL4vhFOPsUeV9O6EN8odni6YepDGicYApcJ4Zy5opv/pub?gid=1790927668&single=true&output=tsv');
echo 'version:   ',PHP_VERSION,"\n";
echo 'mb_strlen: ',mb_strlen($data),"\n";
echo substr(print_r($data, true), 0, 50),"\n";


Expected result:
----------------
