【问题描述】：
您好，我有一个名为“BookPage”的表格，其列：“PageText”
我已经在“PageText”列上设置了搜索（参见下面的代码）。现在，当用户搜索关键字时，所有结果页面都将显示在另一个页面下方。
如果我可以通过单击某种“下一页”按钮链接将它们移至下一页，我可以在其各个页面上显示每个页面文本。

您好，请看下面的修改代码不起作用，您能告诉我哪里出错了。
修改后的代码
<?php
// include MySQL-processing classes
require_once 'mysql.php';
try{
// connect to MySQL
$db=new MySQL(array('host'=>'',''=>'','password'=>'','database'=>''));
//page
if (isset($_GET['page'])) {
$page_no = $_GET['page'];
$next_pg = $page_no + 1;
} else {
$page_no = 0;
$next_pg = 1;
}
$searchterm=$db->escapeString($_GET['searchterm']);
$result=$db->query("SELECT * FROM BookPage WHERE (PageText) like \"%$searchterm%\" ORDER BY BookId ASC LIMIT 0, $page_no");
if(!$result->countRows()){
echo '<div class="maincontainer"><h2>No results were found. Go back and try a new search.</h2></div>'."n";
}
else{
// display search results
echo '<div class="maincontainer"><h2>Your search criteria returned '.$result->countRows().' results.</h2>'."n";
while($row=$result->fetchRow()){
$searchvalue = implode('<span style="color:green;font-weight:800;background-color:yellow;">'.$_GET['searchterm'].'</span>',explode($_GET['searchterm'],$row['PageText']));
echo '<div class="rowcontainer"><p><strong>Book Id:
</strong>'.$row['BookId'].'<p><p><strong>Page Id:

}
}
echo '</div>';
