PHP 中的阿拉伯文文本未从 TextBoX 中搜索到

Question

下面的代码根据在文本框中输入的员工编号或名字搜索员工，但我的名字是阿拉伯语，但不匹配。所附图片在 broser 上显示为阿拉伯语，但不是通过文本框搜索我不知道为什么

Answer 1

现代版本的 PHP 可能不需要这样做，但在文件的第一行添加以下内容：

<?php
    header('Content-Type: text/html; charset=utf-8');
    mb_internal_encoding('UTF-8');
    mb_http_output('UTF-8');
?>

Answer 2

您应该检查数据库表的默认排序规则。我经常与韩国角色一起工作，我总是确保一切都设置为 utf8。（HTML / PHP headers 和数据库表整理）。
