PHP面向对象的使用教程 简单数据库连接
这个PHP的数据库连接类,应该算是最简单的一个连接类了,也是最好明白的一个连接类.作为开始PHP面向编程之旅的一个开始吧.我看了很多网上流传的MYSQL数据库连接类,都太复杂拉.以我己见,真的没必要搞得那么复杂,一个小小的数据库连接.
下面是我的写的类:
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 = "text";//使用的数据库
var $conn; //数据库连接;
var $result; //结果集
var $mysql ="select * from text"; //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;
}
}//类结束,开始调用类来读mysql数据库数据.
$bb = new createdb; //类实例化
$bb->createconn();// 调用类的连接
$bb->getresule(); //调用类得到结果集
while($bb->getrow()){ //调用类创建指针向前读循环读数据,
echo($bb->row["voteid"]);
echo($bb->row["vote"]);
}
?>
这个是放写好的,没优化.不过呢,调试好了可以使用.以后我都会继续写多几个教程类,想文件上传或其他的,一步一步教大家.
还有css+div布局教程和实例,再以后的日子里我也会慢慢教大家.其实做网站真的好累
太多东西学了

PHP 8.4 brings several new features, security improvements, and performance improvements with healthy amounts of feature deprecations and removals. This guide explains how to install PHP 8.4 or upgrade to PHP 8.4 on Ubuntu, Debian, or their derivati

Visual Studio Code, also known as VS Code, is a free source code editor — or integrated development environment (IDE) — available for all major operating systems. With a large collection of extensions for many programming languages, VS Code can be c

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

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,

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.

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.
