PHP读取MySQL数据代码～呢？
新建view.php文件，其内容为：
复制代码 代码如下:
?php
$link=mysql_connect("localhost","root","之前的管理员密码");
if(!$link) echo "没有连接成功!";
else echo "连接成功!";
?
这样，我们便连接上了MySQL数据库，接下来，就是数据读取部分的代码，根据我的MySQL数据源表结构的介绍，我们试验性的来读取：
depart varchar(45) 部门名称
ename varchar(45) 员工姓名
pcname varchar(45) PC名称
这三段数据。
在view.php中紧接着前边的代码继续写：
复制代码 代码如下:
?php
mysql_select_db("infosystem", $link); //选择数据库
$q = "SELECT * FROM info"; //SQL查询语句
mysql_query("SET NAMES GB2312");
$rs = mysql_query($q, $link); //获取数据集
if(!$rs){die("Valid result!");}
echo "table";
echo "trtd部门名称/tdtd员工姓名/tdtdPC名称/td/tr";
while($row = mysql_fetch_row($rs)) echo "trtd$row[1]/tdtd$row[2]/tdtd$row[3]/td/tr"; //显示数据
echo "/table";
mysql_free_result($rs); //关闭数据集
?
其中，“infosystem”为数据库名，“info”为表名。大家可以根据自己的情况酌情修改。
接着，运行它~怎么样~数据是不是顺利被读取了呢？
谁能帮我这一段关于mysql的php代码
能不能说详细点啊？怎么帮，干什么。
?php
$lin = mysql_connect("","",""); //链接数据库
$shujuku1="create database music"; //创造一个数据库
mysql_query($shujuku1);
mysql_select_db('music',$lin) or die(mysql_error); //选择一个数据库
$biao1="create table exomusic(m_name varchar(50),m_zhuanji varchar(50),m_singer varchar(20))"; //创造一个数据表
mysql_query($biao1);
$tianjiashuju="insert into exomusic(m_name,m_zhuanji,m_singer) values('paoxiao','xoxo','exo')";//执行操作
mysql_query($tianjiashuju);
echo "数据库初始化成功！"
?
php中用 mysql 查询整张表数据的代码？
?php
$conn=mysql_connect('localhost','root','root') or die("连接失败").mysql_error();//连接数据库
$select=mysql_select_db('数据库名称',$conn) or die("选择失败").mysql_error();//选择数据库
$ss="set names gbk";
$aa=mysql_query($ss);//设置显示中文
$str="select * from 表名";
$recstr=mysql_query($str);//执行查询
$row=mysql_fetch_row($recstr);
while($row)
{ echo $row[0].$row[1].$row[2];
$row=mysql_fetch_row($recstr);
?
php调用mysql存储过程，如何实现。 我的代码如下：
mysql存储过程返回2个资源，第一个是执行信息，第二个是存储过程返回结果。
mysql_*系列函数无法获取超过1个资源，需使用mysqli或PDO代替。
PDO：
$stmt = $db-prepare("CALL pro_rb_save(?,?,@return_msg);");
$stmt-bindParam(1, $a);
$stmt-bindParam(2, $b);
$stmt-execute ();
$outputArray = $db-query("select @return_msg")-fetch(PDO::FETCH_ASSOC);
var_export($return_msg);
php关于mysql的代码？？
$mysql_server_name = "localhost";//数据库服务器名称
$mysql_username = "root";// 连接数据库用户名
$mysql_password = "";// 连接数据库密码
$mysql_database = "";// 数据库的名字
$conn = mysql_connect($mysql_server_name,$mysql_username,$mysql_password) or die("无法连接服务器!");
mysql_select_db($mysql_database,$conn) or die("无法连接数据库!");
mysql_query('set names gbk');//设定字符集
date_default_timezone_set('Asia/Shanghai');//设置中国时区
$result = mysql_query("*******",$conn);//连接数据库
$num = mysql_num_rows($result);//获取总数
while ($rs = mysql_fetch_array($result)){
循环输出
}
mysql_close($conn);//关闭数据库
