Sending emails with PHP is best implemented with powerful classes such as PHPMailer . Convenient wrapper functions make it possible to use UTF-8 content, embed images and send encrypted attachments with just a few lines of code. If you want to save yourself the overhead and, contrary to the recommendation, use the PHP function mail () , you will run into problems when using umlauts and UTF-8 at the latest.
After calling the function with
mail(
"vieldav@gmx.de", // Empfänger
"ä ö ü ß", // Betreff
"ä ö ü ß", // Inhalt
"From: ä ö ü ß <david@vielhuber.de>" // Header (Absender)
);in a UTF-8 encoded file already leads to problems in the inbox: Outlook 2013 is still gracious and displays everything correctly:
But GMX does not forgive the missing headers and shows a bad subject, sender and content:
If you send the correct headers (for example with base64_encode), you get
mail(
"vieldav@gmx.de", // Empfänger
"=?UTF-8?B?".base64_encode("ä ö ü ß")."?=", // Betreff
"ä ö ü ß", // Inhalt
"Content-type: text/plain; charset=utf-8\r\n"
."From: =?UTF-8?B?".base64_encode("ä ö ü ß")."?=<david@vielhuber.de>" // Header (Absender)
);and finally GMX also shows a correct display:
