Question

我正在尝试INSERT mysql数据库字段中的标题类型char（255），如下所示

$text = 'Лига Справедливости Кризис двух Миров (Justice League Crisis on Two Earths)';

$stmt = mysqli_prepare($con, "INSERT INTO temp (title) VALUES (?)");
mysqli_stmt_bind_param($stmt, 's', $text);
mysqli_stmt_execute($stmt);
printf("%d Row inserted.\n", mysqli_stmt_affected_rows($stmt));
mysqli_stmt_close($stmt);

但是当我在数据库中看到插入的值时，它显示空

为什么？我该如何解决？

我试过

1）

if (!mysqli_set_charset($con, "utf8")) {
    printf("Error loading character set utf8: %s\n", mysqli_error($con));
    die();
}

2）

$text = @iconv('UTF-8', 'UTF-8//IGNORE', $text);

尝试在php中使用urlencode()函数。使用下面的代码

$text = urlencode('Лига Справедливости Кризис двух Миров (Justice League Crisis on Two Earths)');

$stmt = mysqli_prepare($con, "INSERT INTO temp (title) VALUES (?)");
mysqli_stmt_bind_param($stmt, 's', $text);
mysqli_stmt_execute($stmt);
printf("%d Row inserted.\n", mysqli_stmt_affected_rows($stmt));
mysqli_stmt_close($stmt);

获取数据时，只需使用urldecode（）函数解码值

<?php
 $text = urlencode('Лига Справедливости Кризис двух Миров (Justice League Crisis on Two Earths)');
echo $text."<br>"; // will print the encoded text
echo urldecode($test); // Will print the decoded text

希望这有助于你
