PHP and Russian Letters

Question

What is happening with Russian letters when sending via PHP request to ... a mail, by e.g.? the "hardcoded" russians letters are displayed properly, but from the Form's textboxex with hieroglyphs:

HTML page:

<tr>
 <td style="width: 280px">Содержание работ</td>
 <td><input type="text" id="workContent"/></td>
</tr>

PHP page:

$WorkContent = $_REQUEST["workContent"]; //Содержание работ
// ...
$WorkContentLabel = "Содержание работ";
// ...
$message .= $WorkContentLabel . ":\t" . $WorkContent . "\n";
// ...
// email stuff (data below changed)
$to = "[email protected]";
$from = "[email protected]";
$from_header = "From: Russian site command ";

$subject = "Message with russian letters";
$subject = '=?utf-8?B?'.$subject.'?=';
$message .= $subject;

// send message
mail($to, $subject, $message, $from_header);

User enter some content in the textbox: alt text http://lh3.ggpht.com/_1TPOP7DzY1E/S1y6Y0wb9tI/AAAAAAAAC88/OkdMQkO47HQ/s800/works.png

and the submits the form.

What do I receive (in GMAIL):

Содержание работ:       1)Содержание 2)RABOT

So, hard-coded Russian text - OK, sent by the form Russian text - NOK, sent by the form ASCII text - OK.

Does somebody know what could be the cause of that strange behavior with the encoding?

EDIT: used

$subject = "  оборудования  - subject with russian letters";
$subject = '=?UTF-8?B?' . base64_encode($subject) . '?=';
$message .= $subject;

obtains a subject like �����������ÿ - subject with russian letters http://lh6.ggpht.com/_1TPOP7DzY1E/S1zFqFe9ohI/AAAAAAAAC9E/PZ7C4JtEHTU/s800/subject.png

Answer 1

You need to base64_encode() your $subject, like this:

$subject = '=?UTF-8?B?' . base64_encode($subject) . '?=';

Make sure you're also saving your .php file encoded as UTF-8 no BOM.

Answer 2

Check your encodings:

1. HTML encoding (in the <meta http-equiv..> tag)
2. PHP/HTML/template file encoding (what encoding your editor saves the file in)
3. Database encoding (if applicable) (in what encoding the data in the tables is in)
4. Database connection encoding (if applicable) (what encoding is used for database connections)

and use UTF-8 for everything.
