SELECT * FROM表where'column like'％variable％' - 任意順序的多個單詞

Question

我已經爲使用php查詢數據庫的同事編寫了一個快速搜索頁面。它們的字符串被命名爲$ wordvariable（他們也摘棗等，但是這不是這裏重要的），這裏是我在做什麼至今：

$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，這只是搜索的話，他們在自己有訂單類型鍵入它們，例如搜索「堆棧溢出」會發現「堆棧溢出」，但不會找到「溢出堆棧」。我希望我的措辭這個正確的，任何幫助，將不勝感激

Answer 1

是這樣的：

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

短路故障，只是explode的$wordvariable的空間，然後implode對短語的個別單詞，你想。

更詳細，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

更新你的代碼就像這裏：

$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());
