搜索引擎和分页

你好朋友我想知道如何在搜索引擎中添加分页。我已经尝试了很多次，在搜索引擎中添加分页，但每次我都失败了。是否有任何人谁修改我下面的代码添加分页：搜索引擎和分页

的index.php

<?php include 'func.inc.php'; ?> 

<html> 

<head> 
<title>Search</title> 
</head> 

<body> 

<h2> Search </h2> 

<form action="" method="POST"> 
     <p> 
      <input type="text" autocomplete="off" name="keywords" /> <input type="submit" value="Search" /> 
     </p> 
</form> 
<?php 
if (isset($_POST['keywords'])) { 
$suffix = ""; 
$keywords = mysql_real_escape_string (htmlentities (trim($_POST['keywords']))); 

    $errors = array(); 

    if (empty($keywords)) { 
     $errors[] = 'Please enter a search term'; 
    } else if (strlen($keywords)<3) { 
     $errors[] = 'Your search term must be three or more character'; 
    } else if (search_results($keywords) === false) { 
     $errors[] = 'Your search for ' .$keywords. ' returned no result'; 
    } 

    if (empty($errors)) { 
     $results = search_results ($keywords); 
     $results_num = count ($results); 

     $suffix = ($results_num !=1) ? 's' : ''; 

     echo '<p> Your search for <strong>', $keywords,'</strong> returned <strong>',$results_num,'</strong> result',$suffix,'</p>'; 
     foreach($results as $result) { 
      echo '<p><strong><a href="',$result['url'],'">', $result['title'],'</a></strong> <br>', $result['description'],'...<br>', $result['url'],'</p>'; 
      } 

    } else { 
    foreach ($errors as $error) { 
     echo $error, '</br>'; 
    } 
     } 

    } 

?> 


</body> 
</html>

func.inc.php

<?php 
include 'db.inc.php'; 

function search_results($keywords) { 
    $returned_results = array(); 
    $where =""; 

    $keywords = preg_split('/[\s]+/', $keywords); 
    $total_keywords = count($keywords); 

    foreach ($keywords as $key=>$keyword) { 
     $where .="`keywords` LIKE '%$keyword%'"; 
     if ($key != ($total_keywords - 1)) { 
     $where .= "AND"; 
     } 
    } 

    $results = "SELECT `title`, LEFT(`description`, 70) as `description`, `url` FROM `articles` WHERE $where"; 
    $results_num = ($results = mysql_query($results)) ? mysql_num_rows($results): 0; 

    if ($results_num === 0) { 
    return false; 
    } else { 

    while ($results_row = mysql_fetch_assoc($results)) { 
     $returned_results[] = array(
        'title' => $results_row['title'], 
        'description' => $results_row['title'], 
        'url' => $results_row['url'] 


     ); 
    } 

    return $returned_results; 
} 
} 

?>

，我有一个问题，使关闭本部门顶部的关闭按钮。

我修改函数签名，包括页码和每页结果数：

function search_results($keywords,$pagenum,$resultsperpage) {

，然后修改SQL拔出只为有问题的页面结果：

$startresult=($pagenum-1)*$resultsperpage; 
$results = "SELECT `title`, LEFT(`description`, 70) as `description`, `url` FROM `articles` WHERE $where LIMIT $startresult,$resultsperpage";

（假设你会编号从1开始页）

然后，所有你需要的是一个链接，让用户选择他们的页面的列表。我通常会使用GET变量（因为这可能是searchpage.php?p=1），所以您必须按照您的搜索条件进行清理。
