整合了前面的PHP数据库连接类~~做成一个分页类!
不知道学PHP有没有前途~哎越写越没劲
Class createdb //类的开始
{
var $db= "localhost";//数据库地址;
var $dbname = "root";//用户名;
var $dbpwd = "";//密码;
var $dbtable = "mysql";//使用的数据库
var $conn; //数据库连接;
var $result; //结果集
var $mysql; //执行的mysql
var $row; //结果集中找数据
function createconn() //这个类方法是开始一个conn连接,然后开始选择数据库
{
$this->conn = mysql_connect($this->db,$this->dbname,$this->dbpwd);
mysql_select_db($this->dbtable,$this->conn);
}
function getresule() //这个是得到一个结果集
{
$this->result = mysql_query($this->mysql,$this->conn);
}
function getrow() //创建一个向前的结果集指针
{
$this->row = mysql_fetch_array($this->result);
return $this->row;
}
function closedatabase()
{
mysql_close($this->conn);
}
}//类结束,开始调用类来读mysql数据库数据.
//调试数据库连接的代码!不需要的.
/* $bb = new createdb; //类实例化
$bb->createconn();// 调用类的连接
$bb->mysql="select * from friends_conf";
$bb->getresule(); //调用类得到结果集
while($bb->getrow()){ //调用类创建指针向前读循环读数据,
echo($bb->row["confname"]);
echo($bb->row["confvalue"]);
}*/
?>
//分页类~ 继承了上面的方法
Class pagefy extends createdb{
var $nametatol; //总的记录数
var $namemust = 1; //每一页想要显示的记录数
var $pageall;
var $i = 1;
var $m ;
var $p = 8; //需要显示的页码;
var $a;
function gettatol() //取总的记录数方法
{ //先要连接数据库
$this->nametatol = $this->row[0]; //总的记录数
}
function getpage() //取总页数
{
$this->pageall = $this->nametatol % $this->namemust;
if($this->pageall)
{
$this->pageall = (int)($this->nametatol / $this->namemust) + 1;
return $this->a = $this->pageall ;
}
else
{
return $this->a = $this->pageall = (int)($this->nametatol / $this->namemust);
}
}
function num_pl() //页码显示
{
$this->pageall = $this->pageall - ($this->pageall - $this->p);
while($this->pageall)
{
echo("i'>$this->i");
echo(" "); //想显示什么样式自己加
$this->i++;
$this->pageall =$this->pageall -1;
}
}
function get_num_pl() //取的LIMIT的前一个参数(开始ROW数)
{
$this->m = $_GET["n"] * $this->namemust - $this->namemust;
}
function showpage() //显示分页的内容
{
$this->createconn();
$this->mysql="select * from friends_conf limit $this->m ,$this->namemust";
$this->getresule();
while($this->getrow())
{
echo($this->row["confname"]); //你想读出的字段,自己添加
echo($this->row["confvalue"]);
}
}
function firstpage() //首页
{
echo("首页");
}
function backpage() //上一页
{
if($this->i = $_GET["n"] - 1)
{
echo("i'>上一页");
}
}
function nextpage() //下一页
{
$this->i = $_GET["n"] + 1;
if($this->i a)
{
echo("i'>下一页");
}
}
function footpage() //最后一页
{
echo("a'>最后一页");
}
}
?>
$mm = new pagefy;
$mm->createconn();
$mm->mysql="select count(*) from friends_conf";
$mm->getresule();
$mm->closedatabase();
$mm->getrow();
$mm->gettatol();
$mm->getpage();
$mm->num_pl();
$mm->get_num_pl();
$mm->showpage();
$mm->closedatabase();
$mm->firstpage();
$mm->backpage();
$mm->nextpage();
$mm->footpage();
?>
这个类已经调试完成!十分好用~~~~~~~~~~~~~~~~
类就是你的刀~不提前炼好,难到要等打架的时候再去炼呀!~早死人了~~
所有我一有空!就写个方面的功能类~~~~~~
应该来说我这个类~~相对简单~~~看不懂的问~

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
