Question

的MySQL

+----+-------------------+----------+--------------+
| id | address           | city     | state        |      
+----+-------------------+----------+--------------+
| 1  | 13000 highway 244 | keystone | south dakota |
+----+-------------------+----------+--------------+

（顺便说一句，我遗漏了一些专栏以便更容易）

PHP

$string = mysql_real_escape_string('13000 highway 244 south dakota');

$a = mysql_query("

    SELECT * FROM `table` WHERE

    CONCAT_WS(' ', `address`, `city`, `state`) LIKE '%$string%'

");

上述搜索查询不会返回任何结果，只有以下values才能生效：

13000 highway 244 keystone south dakota
13000高速公路244 keystone
keystone south dakota

但是，我还想让以下values工作：

13000 Highway 244 south dakota
13000高速公路keystone
南达科他州高速公路keystone
等

是否可以在不依赖full-text search？

的情况下实现

Answer 1

为什么不这样更明确地编码？

$address = mysql_real_escape_string('13000 highway 244');
$city = mysql_real_escape_string('keystone');
$state = mysql_real_escape_string('south dakota');

$a = mysql_query( '

    SELECT * 
      FROM `table` 
     WHERE (   ( address = ' . $address . ' )
           AND ( city    = ' . $city    . ' )
           AND ( state   = ' . $state   . ' )
           )
        OR ( state   = ' . $state   . ' )
             .. probably more alternatives ...
');

Answer 2

在将字符串传递给查询之前

用通配符替换空格，所以即使“130 dakoda”也可以工作

$string = str_replace( array('*', '?', ' '), array('%', '_', '%'), $string); //Change norm wildcards to mysql format and replace spaces with wildcards
