SELECT * FROM table，其中列為'％variable％' - 任意順序的多個單詞

Question

我為同事們編寫了一個快速搜索頁面，使用php查詢數據庫。 他們的字符串被命名為$ wordvariable（他們也選擇日期等，但這里並不重要），這是我到目前為止所做的：

$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，這只搜索他們按照鍵入的順序鍵入的單詞，例如搜索“堆棧溢出”會發現“堆棧這是溢出”但不會找到“溢出堆棧”。 我希望我的措辭正確，任何幫助將不勝感激

Answer 1

像這樣的東西：

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

短則，就explode了$wordvariable上的空間，然后implode在您需要的短語的各個單詞。

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

像這里更新您的代碼：

$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());
