Throw out a paging class with relatively high functionality (for PHP5.x)

Throw out a paging class with relatively high functionality (for PHP5.x)
Solution
I am afraid that my level is not high, so I never let go of any code. I have been using this class for a long time, and recently rewritten it using object-oriented methods, which is suitable for PHP5.
This class is suitable for paging with database queries and array paging. Here's how to use it.

/*

* Name: Pagination class

* Introduction: Suitable for array paging and paging with sql query

复制代码用法1: 配合数据库使用(例子中配合的是我自己的数据库操作类和模版类) // 这是一个sql查询语句，我们来对它的查询结果作出分页

$sql = "select * from member";

// 读取分页类

require_once("pagebreak.php");

// 分页初始化

// $sql就是上面的查询语句

// 20是每页显示的数量

// Through the initialization of the paging class, this query statement is added with "limit..."

$pagebreak = new PageBreak($sql, 20);

// Generate paging index navigation bar

$navbar = $pagebreak>GetPageInfo().$pagebreak>GetIndexBar();

// Query results (I use my own class here, no more details)

$result = $db>GetFieldsArray($sql)

// Output query results

var_dump($result);

// Output paging index navigation bar

echo $navbar;

Copy code usage 2: Match the array to be output // This is a sql query statement and get the query results

$sql = "select * from member";

$result = $db>GetFieldsArray($sql);

//Read paging class

require_once("pagebreak.php");

//Paging initialization

// $result is the result obtained after the above query

// 20 is the number displayed on each page

// Through the initialization of the paging class, this result array is automatically intercepted into the information content of the corresponding page

$pagebreak = new PageBreak($result, 20);

// Generate paging index navigation bar

$navbar = $pagebreak>GetPageInfo().$pagebreak>GetIndexBar();

// Output query results

var_dump($result);

// Output paging index navigation bar

echo $navbar;

Copy the code and below is the output style,
The first half of the information bar is $pagebreak>GetPageInfo()
The second half of the paging index navigation is $pagebreak>GetIndexBar()

The output content and style can be easily adjusted in the class. It is very simple. If you are interested, you can study it

Great stuff, why don’t you pack it into a package for easy study:$

This is similar to news list paging. It is not news content paging... This is [url=http://www.phpchina.cn/bbs/viewthread.php?tid=12999] link tag http://www .phpchina.cn/bbs/viewthread.php?tid=12999[/url] is the paging of the content..

Very good
There is code
There is annotation
There are application examples

I very much hope that everyone will use this form to send codes

I have a question, it’s like this ordy by...where is it written?
If you don’t understand, ask 1

Why can’t the page navigation be output? Can you please introduce it in detail! I’m a newbie!
D8888D’s reply content
Why are there so many? :(

Except for the limit....information, everything else is in $sql.
The SetSqlQuery method can automatically add limit.... content to the $sql statement.
