我知道，它被问了十几次，但我唯一想要的就是使用php脚本将一个像'Ä'这样的德文字母插入到数据库中，使用现有的解决方案无法正常工作。
<?php
header('Content-type: text/html; charset=utf-8');
$con = mysqli_connect("localhost", "username", "password");
mysqli_set_charset($con, "utf8mb4");
mysqli_select_db($con, "database");
mysqli_query($con, "SET SESSION CHARACTER_SET_RESULTS =utf8mb4;");
mysqli_query($con, "SET SESSION CHARACTER_SET_CLIENT =utf8mb4;");
mysqli_query($con, "SET NAMES 'utf8mb4';");
mysqli_query($con,
"SET character_set_results = 'utf8',
character_set_client = 'utf8',
character_set_connection = 'utf8',
character_set_database = 'utf8',
character_set_server = 'utf8';");
$title = 'Ö';
$result = mysqli_query($con,
"INSERT INTO Test (Title)
VALUES ('" . utf8_encode($title) . "');");
#Doesn't work, this was inserted: Ã
?>
“Title”列的字符集设置为utf8mb4_general_ci，表格本身设置为utf8_general_ci。 MySQL Server版本是5.5.31 MySQL Charset是UTF-8 Unicode
有人知道我做错了什么，或者我错过了什么？
