What happened:

you had utf8-encoded data (good)

你有utf8编码的数据(好)

SET NAMES latin1 was in effect (default, but wrong)

SET NAMES latin1生效(默认,但错误)

the column was declared CHARACTER SET latin1 (default, but wrong)

该列被声明为CHARACTER SET latin1(默认,但错误)

As you INSERTed the data, it was converted to latin1, which does not have values for Arabic (Kurdish/Farsi/etc) characters, so question marks replaced them.

当您插入数据时,它被转换为latin1,它没有阿拉伯语(库尔德语/波斯语/等)字符的值,因此问号替换了它们。

The cure (for future INSERTs):

治愈(对于未来的INSERT):

utf8-encoded data (good)

utf8编码数据(好)

mysqli_set_charset('utf8') (or whatever your client needs for establishing the CHARACTER SET)

mysqli_set_charset('utf8')(或客户端建立CHARACTER SET所需的任何内容)

check that the column(s) and/or table default are CHARACTER SET utf8

检查列和/或表的默认值是CHARACTER SET utf8

If you are displaying on a web page, <meta...utf8> should be near the top.

如果您在网页上显示, 应该在顶部附近。

The discussion above is about CHARACTER SET, the encoding of characters. Now for a tip on COLLATION, which is used for comparing and sorting.

上面的讨论是关于CHARACTER SET,字符的编码。现在获取有关COLLATION的提示,用于比较和排序。

To double check that the data is stored correctly, do SELECT col, HEX(col)....
ه‌رچوون should come back D987E2808CD8B1DA86D988D988D986
Arabic characters in utf8 have hex of D8xx or D9xx.

要仔细检查数据是否正确存储,请执行SELECT col,HEX(col)....هرچوون应该返回D987E2808CD8B1DA86D988D988D986 utf8中的阿拉伯字符具有D8xx或D9xx的十六进制。

(utf8mb4 works just as well as utf8; either works for Arabic.)

(utf8mb4和utf8一样好用;或者适用于阿拉伯语。)

Bad news: The data that was inserted and turned into '???' cannot be recovered.

坏消息:插入的数据变成'???'无法恢复。

put the below code in the connection PHP file then set collation in phpmyadmin (mysql) to utf8_general_ci or utf8_unicode_ci:

将以下代码放在连接PHP文件中,然后在phpmyadmin(mysql)中将collation设置为utf8_general_ci或utf8_unicode_ci:

<?php
$servername="localhost";
$username="root";
$password="";
$databasename="ab1";
$conn = new mysqli($servername, $username, $password, $databasename);
if ($conn->connect_error) {
die("connection failed" .$conn->connect_error);
}else
echo "connection sucssessfullly";
$conn->query("SET NAMES 'utf8'");
$conn->query("SET CHARACTER SET utf8");
?>
