Question

<?php
ini_set('display_errors', 0);
$search = $_GET ['search'];
mysql_connect("localhost", "root", "gokul");
mysql_select_db("search123");
$query    = mysql_query("SELECT * FROM search WHERE name LIKE '%" . $queryString . "%'");
$foundnum = mysql_num_rows($query);
if ($foundnum == 0) {
    echo "Sorry, there are no matching result for <b>$search</b>.</br></br>1.
Try more general words. for example: If you want to search 'how to create a website' 
then use general keyword like 'create' 'website'</br>2. Try different words with similar
 meaning</br>3. Please check your spelling<br/>4.PLEASE DON'T USE SPACES";
}
else {
    echo "$foundnum results found !<p>";
    $row = mysql_fetch_assoc($query);
    {
        $title = $runrows ['title'];
        $desc  = $runrows ['description'];
        $url   = $runrows ['url'];
        echo "<a href=$row[url]>$row[name]</a><br><font color=green>$row[url]</font><br>$row[desc]<br/>";
    }
}
?>

这是我的搜索引擎脚本。此脚本仅显示一个结果。如何更改它以使用php

显示multy结果

Answer 1

更改为：

while ($row = mysql_fetch_assoc($query)) {
    $title = $runrows ['title'];
$desc = $runrows ['description'];
$url = $runrows ['url'];
echo "<a href=$row[url]>$row[name]</a><br><font color=green>$row[url]</font><br>$row[desc]<br/>";

}

Answer 2

对Elen（正确）答案的更多解释。 mysql_fetch_assoc（）从结果集中获取一条记录。您可以反复调用它来依次获取每条记录。一旦你获取了最后一条记录“$ row = mysql_fetch_assoc（$ query）”就会失败。因此，您可以在 while 循环中使用该表达式来获取每一行，并在完成后停止。

Answer 3

这里mysql_fetch_assoc您只是获取结果，而不是循环它们。 http://php.net/manual/en/function.mysql-fetch-assoc.php

使用foreach()或任何循环方法获得更多结果。
