不使用php

Question

在我的.html文档中，我的表单是

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 

在.php文件中，我连接到我尝试使用

的数据库

mysql_set_charset('utf8');   
// and 
// <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

和此：

header('Content-Type: text/html; charset=utf-8'); 

数据库行包含排序规则：utf8_unicode_ci和字符集utf8 所以我的问题是，当我从html表单通过php发送代码时，我在我的数据库中看到这个：Ð〜збÐμÑ€ÐμÑ 这是.php文档代码：

    <?php
// header('Content-Type: text/html; charset=utf-8');
header('Content-Type: text/html; charset=utf8');

// mysql_set_charset('utf8_unicode_ci');  
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "dbname";

$name = $_POST['name'];

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// mysql_set_charset('utf8');
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO oglasi (Name)
VALUES ('$name')";

if ($conn->query($sql) === TRUE) {
    echo "";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}   
$conn->close();
// mysql_set_charset('utf8');
?>

Answer 1

PROCEDURAL：

mysqli_set_charset（连接，字符集）;

$con=mysqli_connect("localhost","my_user","my_password","my_db");
mysqli_set_charset($con,"utf8");

OOP：

$mysqli = new mysqli("localhost", "my_user", "my_password", "test");
/* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
    printf("Error loading character set utf8: %s\n", $mysqli->error);
    exit();
} else {
    printf("Current character set: %s\n", $mysqli->character_set_name());
}

在执行插入查询之前，您应该运行：

$conn->query("SET NAMES 'utf8'");
