如何从 sql 中设置 unicode 数据？

Question

如何将 unicode utf-8 设置为此 scipt 群发邮件发件人

HTML：

<form action="sendemail.php" method="post">
<label>Subject of email:</label><br><input type="text" name="subject" id="subject"/><br>
<label>Body of email:</label><br><textarea name="body" id="body" rows="10" cols="70"></textarea><br>
<input type="submit" name=submit value="Submit"/>
</form>

PHP：

<?php

$user = "user_name"; 
$password = "password"; 
$host = "host_name"; 
$dbase = "database_name"; 
$table = "table_name"; 

$from= 'email_address';

$subject= $_POST['subject'];
$body= $_POST['body'];

$dbc= mysqli_connect($host,$user,$password, $dbase) 
or die("Unable to select database");

$query= "SELECT * FROM $table";
$result= mysqli_query ($dbc, $query) 
or die ('Error querying database.');

while ($row = mysqli_fetch_array($result)) {
$first_name= $row['first_name'];
$last_name= $row['last_name'];
$email= $row['email'];
$msg= "Dear $first_name $last_name,\n$body";
mail($email, $subject, $msg, 'From:' . $from);
echo 'Email sent to: ' . $to. '<br>';
}
mysqli_close($dbc);
?>

$last_name 是 ėkovič，显示邮件 - ?kovi？

附言设置 character_set_client='utf8'

设置 collat​​ion_connection='utf8_general_ci' 不起作用。

您需要设置character encoding 才能获得相同的效果

set character_set_client='utf8'

set collation_connection='utf8_general_ci'
