Strange error

Hi,

I have a csv file with the following header:

email;username;name;full_name;email_verified;password;profile_photo_path;group;sex

With the following code:

$file = fopen($filename, "r");
$header_csv = fgets($file);
dd($header_csv);

I get (note the space between e and mail):

"e mail;username;name;full_name;email_verified;password;profile_photo_path;group;sex\r\n"

If I change the word email to another one, the same problem occurs. Example: name --> n same

Can someone has an idea why this happens?

Thanks
