通过PHP连接MYSQL数据库、创建数据库、创建表

通过PHP连接MYSQL数据库


$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_select_db("table" ,$conn) or die ("找不到数据源");

-----------------------------------------------------------------------
通过PHP创建MYSQL数据库

$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_create_db("webjx") or die("无法创建数据库");
$sqlstr = "create database other_webjx";
mysql_query($sqlstr) or die("无法创建,一般请检查权限什么的");
----------------------------------------------------------------------------
创建mysql的表

$conn = mysql_connect("localhost","root","password") or die("无法连接数据库");
mysql_select_db("webjx",$conn) or die("无法连接数据库webjx");
$sql = "create table webjx_table(
ids integer not null auto_increment ,
primary key(ids)
)";
$mysql_query($sql) or die(mysql_error());

一个创建表的典型例子：

<?php

$conn=mysql_connect("localhost","root","");
$sql_select=mysql_select_db("up");

$sql_create="create table message(";
$sql_create.="id bigint UNSIGNED AUTO_INCREMENT Primary key,";
$sql_create.="title varchar(100),";
$sql_create.="category varchar(3)";
$sql_create.=")";

mysql_query($sql_create);

?>
