这是一款简单实用的php分页代码,同时也很好的利用的类的构造函数来实例分页的初始化,好了下面我们来看看这款代码如何吧,代码如下:

1. class page extends mysql
2. {
3. public $page;
4. public $page_size;
5. private $table;
6. private $condition;
7. private $limit;
8. private $href;
9. private $action_value;
10. private $url_value;
11. //分页初始化
12. function __construct($page,$page_size,$table,$condition,$limit,$href,$action_value,$url_value)
13. {
14. $this->page=$page;
15. $this->page_size=$page_size;
16. $this->table=$table;
17. $this->condition=$condition;
18. $this->limit=$limit;
19. $this->href=$href;
20. $this->action_value=$action_value;
21. $this->url_value=$url_value;
22. $this->get_page();
23. }
24. /**
25. * get the page's value判断当前在第几页
26. */
27. function get_page()
28. {
29. if($this->page=="")
30. {
31. $this->page=1;
32. }
33. return $this->page;
34. }
35. /**
36. * page main code //调用转到指定的分页代码号。
37. */
38. function go_page()
39. {
40. if($this->page!="")
41. {
42. $reslut=mysql::fn_select($this->table,'count(*) as `total`',$this->condition,'',$this->limit);
43. $rs=mysql::fetch_array($reslut);
44. $message_count=$rs['total']; //get the messages's count number
45. $page_count=ceil($message_count/$this->page_size); //get the page's count number
46. $offset=($this->page-1)*$this->page_size; //get the first value of sql's limit
47. if($message_count<=$this->page_size)
48. {
49. $page_code=array("","","","");
50. }
51. else if($this->page==1)
52. {
53. $page_code=array("",
54. "",
55. "<a name=code href=".$this->href."?page=".($this->page+1)."&action=".$this->action_value."&".$this->url_value.">下一页</a>",
56. "<a name=code href=".$this->href."?page=".$page_count."&action=".$this->action_value."&".$this->url_value.">尾页</a>");
57. }
58. else if($this->page==$page_count)
59. {
60. $page_code=array("<a name='code' href=".$this->href."?page=1&action=".$this->action_value."&".$this->url_value.">首页</a>",
61. "<a name='code' href=".$this->href."?page=".($this->page-1)."&action=".$this->action_value."&".$this->url_value.">上一页</a>",
62. "",
63. "");
64. }
65. else
66. {
67. $page_code=array("<a name='code' href=".$this->href."?page=1&action=".$this->action_value."&".$this->url_value.">首页</a>",
68. "<a name='code' href=".$this->href."?page=".($this->page-1)."&action=".$this->action_value."&".$this->url_value.">上一页</a>",
69. "<a name='code' href=".$this->href."?page=".($this->page+1)."&action=".$this->action_value."&".$this->url_value.">下一页</a>",
70. "<a name='code' href=".$this->href."?page=".$page_count."&action=".$this->action_value."&".$this->url_value.">尾页</a>");
71. }
72. $page_info=array(
73. "message_count"=>$message_count,
74. "page_count"=>$page_count,
75. "offset"=>$offset,
76. "page_size"=>$this->page_size,
77. "page_now"=>$this->page,
78. "page_first"=>$page_code[0],
79. "page_up"=>$page_code[1],
80. "page_next"=>$page_code[2],
81. "page_one_last"=>$page_code[3]
82. );//开源代码phpfensi.com
83. return $page_info;
84. }
85. }
86. }

php分页代码调用方法,代码如下:

1. $page = new page('',10,'`cy0871_users_info`','index.php',1,'','','user);
2. print_r ($page->go_page());
3. $page_info = $page->go_page();
4. echo $page_info['page']."<br/>";
5. echo $page_info['page_size'];
