您好我有一个搜索表单，我正在搜索该表单的结果。 它适用于获取数据，但我想将这些结果放入分页或加载更多数据。 iam newbie to pagination.below是mycode。如何将分页应用于下面的代码。
<form method="post" action="searchresults_t1.php" enctype="multipart/form-data" >
<table width="60%" padding="8px" >

<td><label><font style="font-size:20px">Run No:</font></label> </td>

最简单的分页
原始答案：Simple PHP Pagination script
try {

$total = $dbh->query('

COUNT(*)
FROM

')->fetchColumn();
// How many items to list per page
$limit = 20;
