SELECT * FROM表where'column like'％variable％' - 任意顺序的多个单词

Question

我已经为使用php查询数据库的同事编写了一个快速搜索页面。它们的字符串被命名为$ wordvariable（他们也摘枣等，但是这不是这里重要的），这里是我在做什么至今：

$wordvariable = explode(" ", $wordvariable); 
$wordvariable = implode("%", $wordvariable); 
$Query = mysql_query(
    "SELECT * FROM table 
    WHERE (column1 like '%$wordvariable%' or column2 like '%$wordvariable%') 
    AND logdatex between $TimeEarlier and $TimeNow" 
) or die(mysql_error()); 

然而，这只是搜索的话，他们在自己有订单类型键入它们，例如搜索“堆栈溢出”会发现“堆栈溢出”，但不会找到“溢出堆栈”。我希望我的措辞这个正确的，任何帮助，将不胜感激

Answer 1

是这样的：

$where = "WHERE column1 LIKE '%" . implode("%' OR column1 LIKE '%", explode(" ", $wordvariable)) . "%'"; 

短路故障，只是explode的$wordvariable的空间，然后implode对短语的个别单词，你想。

更详细，包括column2：

$words = explode(" ", $wordvariable); 
$list1 = implode("%' OR column1 LIKE '%", $words); 
$list2 = implode("%' OR column2 LIKE '%", $words); 

echo $where = "WHERE (column1 LIKE '%$list1%') OR (column2 LIKE '%$list2%')"; 

Answer 2

更新你的代码就像这里：

$wordvariable = explode(" ", $wordvariable); 

$Query = mysql_query(
    "SELECT * FROM table 
    WHERE (column1 like '%" . implode("%' OR column1 Like '%", $wordvariable) . "%' 
    OR column2 like '%" . implode("%' OR column2 Like '%", $wordvariable) . "%') 
    AND logdatex between $TimeEarlier and $TimeNow" 
) or die(mysql_error());
