php与Mysql之间的关系以及一些简单的操作

先贴代码

    
        <title>数据库相关</title>
    


<span>php

    </span><span>$con</span> = <span>mysql_connect</span>("localhost","root","root"); <span>//</span><span>链接数据库</span>
        <span>if</span>(!<span>$con</span><span>){
            </span><span>die</span>('连接失败！' . <span>mysql_error</span>());       <span>//</span><span>判断是否成功</span>
<span>        }     
        
</span><span>/*</span><span>        if(mysql_query("CREATE DATABASE testdb",$con)){ //通过mysql_query 查询或者发送命令
            echo "创建testdb成功";                   
        }
        else{
            echo "失败原因：" . mysql_error();         //判断是否创建成功
        }
</span><span>*/</span>    
    
        <span>mysql_select_db</span>("testdb",<span>$con</span>);               <span>//</span><span>选择链接刚刚创建的数据库</span>
            
            <span>$sql</span> = "<span>CREATE TABLE Persons               
               (personID int NOT NULL AUTO_INCREMENT, 
                PRIMARY KEY(personID),
                FirstName varchar(15),
                LastName varchar(15),
                Age int)
            </span>";                                        <span>//</span><span>Mysql 语句 创建表</span>
        <span>mysql_query</span>(<span>$sql</span>,<span>$con</span>);                          <span>//</span><span>执行sql语句</span>
        
        
        
    <span>mysql_close</span>(<span>$con</span>);                                <span>//</span><span>关闭mysql连接</span>
    
?> 

关键内容在于

1、链接数据库

2、创建表

3、根据需求充实表内容

以上就介绍了php与Mysql之间的关系以及一些简单的操作，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
