我正在尝试制作一个程序，通过它我可以显示任何特定的关键字（搜索词），在特定日期搜索了多少次。
如果有人正在搜索 Stackoverflow，我想显示其搜索统计信息以获取特定数据。
例如;

at 2013-04-01 -> stackoverflow was searched for 15 times<br>
at 2013-04-02 -> stackoverflow was searched for 28 times<br>
at 2013-04-03 -> stackoverflow was searched for 10 times<br>


我希望现在你会明白我想说什么。，。
现在让我展示一下我为制作这个程序所做的工作。

看到这个代码

<?php
$keyword = null;

if (!empty($_GET['s'])) {


$keyword = stripslashes($_GET['s']);

try {

    $objDb = new PDO('mysql:dbname=test;charset=UTF-8', 'root', '');

    $sql = "INSERT INTO `search` (`keyword`)
            VALUES (:keyword)
            ON DUPLICATE KEY UPDATE `times` = `times` + 1";

    $statement = $objDb->prepare($sql);
    $statement->execute(array(':keyword' => $keyword));

} catch(PDOException $e) {
    echo $e->getMessage();
}


  }


  try {

$objDb = new PDO('mysql:dbname=test;charset=UTF-8', 'root', '');




  $sql = "SELECT `s`.*,
        IF (
            (
                SELECT `id`
                FROM `search` 
                ORDER BY `date` DESC
                LIMIT 0, 1
            ) = `s`.`id`,
            1,
            0
        ) AS `latest`
        FROM `search` `s`
        ORDER BY `date` DESC LIMIT 0, 50";




$statement = $objDb->query($sql);
$result = $statement->fetchAll(PDO::FETCH_ASSOC);

  } catch(PDOException $e) {
echo $e->getMessage();
  }

  ?>

        <?php foreach($result as $row) { ?>
        <tr<?php echo $row['latest'] == 1 ? ' class="active"' : null; ?>>
            <td><?php echo $row['keyword']; ?></td>
            <td class="tar"><?php echo $row['times']; ?></td>
        </tr>
        <?php } ?>
    </table>

 <?php } else { ?>
    <p>There are currently no searches available.</p>
 <?php } ?>

  </section>

  </body>
  </html>


这是一个简单的程序，它将最近搜索的关键字保存在数据库中并显示在网页上，它还显示关键字被搜索的次数。实际上它只是用更新的时间戳替换当前时间戳。
现在任何人都可以帮忙添加一个特定条件来检查今天的日期，然后它将在数据库中添加条目，如果在同一天研究了该特定单词，那么它将仅使用更新的时间戳更新 current_timestamp。我只想根据日期划分最近的搜索查询。


这是在您的数据库中制作此表的代码 

CREATE TABLE IF NOT EXISTS `search` ( <br>
`id` int(11) unsigned NOT NULL AUTO_INCREMENT, <br>
`keyword` varchar(100) NOT NULL, <br>
`times` int(11) unsigned DEFAULT '1', <br>
`date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, <br>
 PRIMARY KEY (`id`), <br> 
 UNIQUE KEY `keyword` (`keyword`) <br>
 ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 AUTO_INCREMENT=301 ; <br>



请用示例数据回复..

怎么样

SELECT keywords, COUNT(*) as no_of_times, date 
FROM search 
GROUP BY date, keywords

这会给你类似的东西

keywords      | no_of_times | date       |
------------------------------------------
stackoverflow |    25       | 2012-10-12 |
meta          |    10       | 2012-10-12 |

我有一个简单的解决方案，我现在可以想到。

$search_term = $_POST['search_term'];
$date = $_POST['date'];

$select = mysqli_query("select * from search where keyword='$search_term' and date='$date'");
$rowCheck = mysqli_num_rows($select);
if($rowCheck>0) {
 $fetch = mysqli_fetch_array($select);
 $times = $fetch['times'];
 $update_query = // RUN UPDATE QUERY HERE
} else {
  // RUN INSERT QUERY HERE
}

希望这可以帮助
