Question

我已经搜索了几个小时的问题，但我找不到适合我的答案，所以...我来了......

我是匈牙利人，我们在我们的语言中使用以下重音字符：áéíóöőúüű（当然还有首都同行）我想在php中进行智能搜索，允许用户输入搜索词，并在MySQl表或搜索字段中查找结果是否具有重音。所以......

我的MySQL表使用的是utf8_hungarian_ci 我可以进行php转换，以便用户输入'Bla'或'blá'，它将返回'bla'，我们正在搜索mySQL数据库。

但我的问题是......我的数据库可能有'blafér'或'bláter'字段条目。但是如果我们用'bla'（来自PHP）进行搜索，它只返回'bla fer'。如何转换我正在搜索的字段'blafér' - ＆gt; 'bla fer'和'bláter' - ＆gt; 'blater'。基本上......

我想摆脱重音字符并将它们变成不重音的字符。但当然，只是为了搜索。请帮忙！谢谢！

<?php 
$search = $_GET["search"]; // May contain áéíóöőúüű
$accented= array("Ö","ö","Ü","ü","ű","Ó","ó","O","o","Ú","ú","Á","á","U","u","É","é","Í","í"," ","+","'","ő", "Ű", "Ő", "ä","Ä","ű","Ű","ő","Ő");
$nonaccented=array("O","o","U","u","u","O","o","O","o","U","u","A","a","U","u","E","e","I","i","_","_","_","o", "U", "O", "a","A","u","u","o","o");
$search = str_replace($accented,$nonaccented,$search);
$query = "SELECT id, name FROM people WHERE name LIKE '%$search%'"; // Database column 'name' may also contain áéíóöőúüű
?>

以下是我的测试结果。你可以与你比较：

CREATE TABLE `test` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(32) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8

表格内容：

mysql> select * from test;
+----+---------+
| id | name    |
+----+---------+
|  1 | bla     | 
|  2 | blater  | 
|  3 | bláter | 
|  4 | bhei    | 
+----+---------+
4 rows in set (0.00 sec)

搜索结果;

mysql> select * from test where name like '%bla%';
+----+---------+
| id | name    |
+----+---------+
|  1 | bla     | 
|  2 | blater  | 
|  3 | bláter | 
+----+---------+
3 rows in set (0.00 sec)

使用重音搜索：

mysql> select * from test where name like '%blá%';;
+----+---------+
| id | name    |
+----+---------+
|  3 | bláter | 
+----+---------+
1 row in set (0.00 sec)

即使使用COLLATE=utf8_hungarian_ci

，我也会得到相同的结果

Answer 2

对我来说，将字符编码设置为utf8_general_ci（或使用＆＃34; _ci＆＃34;的其他内容）就可以了。 _ci表示SQL将匹配搜索，无论是大小写还是重音。
