如何使用mysql数据库在php中创建简单的分页

Question

 <?php 
 include 'connections.php';
 $search = $_POST['searchvalue']; // search value is getting from HTML FORM i.e user entered value
 if(strlen($search)>=1)
   else{
 echo "You searched for <b>$search</b> <hr size='1'></br>";
 $search_exploded = explode (" ", $search);
 $x = "";
 $construct = "";  
 foreach($search_exploded as $search_each)
 {
 $x++;
 if($x==1)
 $construct .="title LIKE '%$search_each%'";
 else
 $construct .="AND title LIKE '%$search_each%'";
 } 
 $construct ="SELECT * FROM books WHERE $construct";
 $run = mysql_query($construct);
 $foundnum = mysql_num_rows($run);
 if ($foundnum!=0)
 while($runrows = mysql_fetch_assoc($run))
 {
 echo $result; // i have more code to print the result instead i am just using '$result' here.....
 }
 }
 }
 ?>

上面是显示搜索结果的代码我在我的页面中成功显示结果，但我想每页只显示三个结果。我想为此开发分页，我在stackoverflow和google搜索逻辑分区，但我厌倦了代码我感觉更复杂我根本不理解分页逻辑。请任何人帮助我如何以简单的方式发展分页？而且我不是php的专家，我只是初学者...提前感谢..
