Question

开头的搜索关键字记录将首先出现。无法正常搜索，请帮帮我......

$terms =explode(" ", $search);
$query = "SELECT * FROM search where ";
$i = 0;
foreach ($terms as $each)
{
$i++;
if ($i == 1)
$query .= "(`title` LIKE '%".$each."%') OR (`website` LIKE '%".$each."%')";

else
$query .= "OR (`title` LIKE '%".$each."%') OR (`website` LIKE '%".$each."%')";
}

您应该查看MySQL的Full Text Search来实现搜索功能，因为它比LIKE运算符更灵活，更高效。

您的表定义看起来像。

CREATE TABLE search (
   id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
   title VARCHAR(200),
   website TEXT,
   FULLTEXT (title,website)
) ENGINE=InnoDB;

然后你的查询会是这样的。

SELECT * FROM search
WHERE MATCH (title,website)
AGAINST ('this is your query' IN NATURAL LANGUAGE MODE)

我还要确保输入已正确转义以阻止SQL Injection Attacks。
