1 Create database table:
create database club;
create table member(
id int(11) not null auto_increment,
no varchar(5) not null,
name varchar(10) not null,
age int(2) not null,
level varchar(10) not null,
sex tinyint(1) not null,
date datetime not null,
primary key(id)
)engine=MyISAM default charset=GB2312;
insert into member(id,no,name,age,level,sex,date)values
(1,'A001','wanxia',30,'hj',1,'2008-04-02 00 :00:00'),
(2,'C022','liyan',29,'zs',1,'2007-05-31 00:00:00'),
(3,' A006','zhangyan',36,'hj',1,'2007-06-20 00:00:00'),
(4,'B052','luanying',42,'bj',1 ,'2007-02-12 00:00:00'),
(5,'A007','duxiang',26,'hj',2,'2008-03-26 00:00:00') ,
(6,'C060','liuyu',38,'zs',1,'2008-10-16 00:00:00');

2 Read data
2.1 Create 01.php
Code
< ;title>Member List
$link=mysql_connect("localhost","root","123"); //Connect to mysql Server
$db=mysql_select_db("club"); //Select database
mysql_query("set names utf8",$link); //Set encoding method
$sql="Select * from member ";
$result=mysql_query($sql,$link); //Execute select query
$num=mysql_num_rows($result); //Get record query
?>

php5和php8的区别在性能、语言结构、类型系统、错误处理、异步编程、标准库函数和安全性等方面。详细介绍:1、性能提升,PHP8相对于PHP5来说在性能方面有了巨大的提升,PHP8引入了JIT编译器,可以对一些高频执行的代码进行编译和优化,从而提高运行速度;2、语言结构改进,PHP8引入了一些新的语言结构和功能,PHP8支持命名参数,允许开发者通过参数名而不是参数顺序等等。

mysql的msi与zip版本的区别:1、zip包含的安装程序是一种主动安装,而msi包含的是被installer所用的安装文件以提交请求的方式安装;2、zip是一种数据压缩和文档存储的文件格式,msi是微软格式的安装包。

在mysql中,可以利用char()和REPLACE()函数来替换换行符;REPLACE()函数可以用新字符串替换列中的换行符,而换行符可使用“char(13)”来表示,语法为“replace(字段名,char(13),'新字符串') ”。

转换方法:1、利用cast函数,语法“select * from 表名 order by cast(字段名 as SIGNED)”;2、利用“select * from 表名 order by CONVERT(字段名,SIGNED)”语句。

本篇文章给大家带来了关于mysql的相关知识,其中主要介绍了关于MySQL复制技术的相关问题,包括了异步复制、半同步复制等等内容,下面一起来看一下,希望对大家有帮助。

在mysql中,可以利用REGEXP运算符判断数据是否是数字类型,语法为“String REGEXP '[^0-9.]'”;该运算符是正则表达式的缩写,若数据字符中含有数字时,返回的结果是true,反之返回的结果是false。

“mysql-connector”是mysql官方提供的驱动器,可以用于连接使用mysql;可利用“pip install mysql-connector”命令进行安装,利用“import mysql.connector”测试是否安装成功。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
