如何搜索多列，此代码搜索单列，请自定义我的代码

$keywords= "search keywords";
$keywords= htmlspecialchars($keywords);    
$keywords= mysqli_real_escape_string($con, $keywords);
$countSql_s = "SELECT *, MATCH(website) AGAINST ('%".$keywords."%') AS score FROM search WHERE MATCH(website) AGAINST ('%".$keywords."%') ORDER BY score DESC";

Answer 1

只需改变你的＆＃34; WHERE＆＃34;包括每列的检查，如下所示：

... WHERE MATCH(website) AGAINST('%".$keywords."%') > 5
AND MATCH(username) AGAINST('%".$keywords."%') > 5
...

Answer 2

您需要将表格更改为：

ALTER TABLE --table name-- ADD FULLTEXT fulltext_search (column1,colum2,column3);

然后你可以像这样搜索：

MATCH (column1,column2) AGAINST ('%".$keywords."%')
