从 2 列中搜索 php mysql

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 并使用此条件 file.exe 获取所有结果。或者 somebode search only .exe 使用 type .exe 获取所有结果 $where .= "title, type LIKE '%$keyword%'";//我这样做没有结果 $where .= "title AND type LIKE '%$keyword%'";//我这样做没有结果 $where .= "title LIKE '%$keyword%' AND type LIKE '%$keyword%'";//我这样做没有结果有人知道我如何获得带有符号“.”的标题类型的结果？？？

Answer 1

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

更新代码

$pos = strpos($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%'";
}
