我试图对 PHP 函数进行 Ajax 调用，以从数据库中提取数据。不过我遇到了问题。

我的查询看起来像这样，

$query = "SELECT * FROM mytable WHERE field LIKE '%$string%'"

然后检查查询返回的行数，但是当我输入 æ ø å 时，我的查询返回 0 行，尽管我知道数据库中有包含 æ ø å 的条目。这是为什么

My trying to make an Ajax call to a PHP function that pulls out data from my database. I've run into a problem though.

My query looks like this

$query = "SELECT * FROM mytable WHERE field LIKE '%$string%'"

I then check on the number of rows returned by the query, but when i type in æ ø å then i my query returns 0 rows, although I know there are entries in the database that have æ ø å.. why is this

就我而言，我必须添加这一行：

mysqli_set_charset($con,"utf8mb4");

in my case, I had to add this line:

mysqli_set_charset($con,"utf8mb4");

将连接设置为使用 UTF-8：

<?php

// MySQLi:

$connection = new MySQLi( /* ... credentials ...*/);
$connection->set_charset("utf8");


// MySQL:
$connection = mysql_connect(/* ... credentials ... */); 
mysql_set_charset("utf8", $connection);

?>

Set the connection to use UTF-8:

<?php

// MySQLi:

$connection = new MySQLi( /* ... credentials ...*/);
$connection->set_charset("utf8");


// MySQL:
$connection = mysql_connect(/* ... credentials ... */); 
mysql_set_charset("utf8", $connection);

?>
