Do I need to send the header "MIME-Version: 1.0"?

And why is it needed?

How literate?

You just need to send an html email without any attachments there

/* получатели */ $to= "Mary <mary@example.com>" . ", " ; //обратите внимание на запятую $to .= "Kelly <kelly@example.com>"; /* тема/subject */ $subject = "Birthday Reminders for August"; /* сообщение */ $message = ' <html> <head> <title>Birthday Reminders for August</title> </head> <body> <p>Here are the birthdays upcoming in August!</p> <table> <tr> <th>Person</th><th>Day</th><th>Month</th><th>Year</th> </tr> <tr> <td>Joe</td><td>3rd</td><td>August</td><td>1970</td> </tr> <tr> <td>Sally</td><td>17th</td><td>August</td><td>1973</td> </tr> </table> </body> </html> '; /* Для отправки HTML-почты вы можете установить шапку Content-type. */ $headers= "MIME-Version: 1.0\r\n"; $headers .= "Content-type: text/html; charset=iso-8859-1\r\n"; /* дополнительные шапки */ $headers .= "From: Birthday Reminder <birthday@example.com>\r\n"; $headers .= "Cc: birthdayarchive@example.com\r\n"; $headers .= "Bcc: birthdaycheck@example.com\r\n"; /* и теперь отправим из */ mail($to, $subject, $message, $headers);

If in the letter you need to specify, for example, Content-Type: (text/plain или text/html) then you need to specify mime . What is and why you need mime can be read here

    This is the standard RFC-822. Currently, any sent email, even if it does not contain any attachments, somehow uses MIME.

    MIME-Version is a required parameter. rfc2822
