PHP的MySQL從2列搜索

Question

$where = "";
$keywords =preg_split('/[\s]+/', $keywords);
$total_keywords = count($keywords);

foreach($keywords as $key=>$keyword) {
    $where .= "`title` LIKE '%$keyword%'";
    if ($key != ($total_keywords - 1)) {
        $where .= " AND ";
    }
}

    $results = "SELECT `id`, `username`, `title`, LEFT(`description`, 90) as `description`, `file`, `code`, `type`, `size`, `date` FROM `files` WHERE $where ORDER BY id DESC LIMIT $start, $per_page";


  $where .= "`title` LIKE '%$keyword%'"; // this case I am searching only in column `title` I want to search too in column `type` with sign '.' I don't know how to include '.' in search result for `type`

示例搜索file.exe，並使用此條件file.exe獲取所有結果。 或只搜索.exe即可獲得所有type .exe $ where。=“ title ， type LIKE'％$ keyword％'”“的結果； //我這樣做是沒有結果的$ where。=” title和type LIKE'％ $ keyword％'“; //我這樣做是沒有結果$ where。=” title LIKE'％$ keyword％'並type LIKE'％$ keyword％'“; //我這樣做是沒有結果有人知道如何獲得標題類型為“。”的結果？

Answer 1

$where .= "`title` LIKE '%$keyword%' OR type LIKE '$type'";

更新的代碼

$pos = strpos($keyword, '.');
if($pos > 0) {
    $parts = explode('.', $keyword);
    $type = array_pop($parts);
    $file = array_pop($parts);
    $where .= "`title` LIKE '%$file%' AND type LIKE '%$type%'";
}
else {
$where .= "`title` LIKE '%$keyword%' OR type LIKE '%$type%'";
}

Answer 2

$where .= "`title` LIKE '%$keyword%' OR type LIKE '%$type%'";
