如何在此查询中使用DISTINCT子句以消除重复结果？

Question

<?php 

  $k = $_GET['K'];

  $terms = explode(" ", $k);

  $query = "SELECT * FROM search WHERE ";

  foreach ( $terms as $each) {

          $i++;

      if($i == 1)

      $query .= "keywords LIKE '%$each%' ";

      else

        $query .= "OR keywords LIKE '%$each%' ";

}

需要（＆＃34; connect.php＆＃34）;

$ query = mysql_query（$ query）;

$ numrows = mysql_num_rows（$ query）;

if（$ numrows＆gt; 0）{

while（$ rows = mysql_fetch_assoc（$ query））{

        $id = $rows['id'];
        $title = $rows['title'];
        $description = $rows['descriptions'];
        $keywords = $rows['keywords'];
        $link = $rows['link'];


        echo "<h2><a href = '$link'> $title </a></h2> 
        $description <br /> <br />";

}

}其他

echo＆＃34;未找到\＆＃34; $ k \＆＃34;＆＃34;;

的结果

mysql_close（）;

你可以这样做

$query = "SELECT DISTINCT *FROM search WHERE ";
