PHP connects to the database and dynamically displays database records_PHP tutorial

This article will introduce a good introductory example of PHP mysql to PHP beginners. We connect to the database and display the record examples in the database. Friends can refer to it.

Connect to a MySQL database

Before you can access and process data in the database, you must create a connection to the database.

In PHP, this task is accomplished through the mysql_connect() function.

Grammar

mysql_connect(servername,username,password);

In the example below, we store the connection in a variable ($con) for later use in the script. If the connection fails, the "die" part will be executed:

// some code

The code is as follows

代码如下	复制代码
$con = mysql_connect("localhost","peter","abc123"); if (!$con)   {   die('Could not connect: ' . mysql_error());   } // some code ?>

Copy code

 代码如下

复制代码

mysql_connect("localhost","root","");
mysql_select_db("cinema");
$_sql="select * from `t_hall`";
mysql_query("set names utf8");//编码设置为utf8
$query=mysql_query($_sql);
echo "

";
echo "";
while($row=mysql_fetch_array($query))
{
//从数据库查询出来的字段
//将数据放到html的表格中

echo "

";
}
echo "

影厅编号	大厅名	座位行	座位列
{$row['HID']}	{$row['HHall']}	{$row['HSeatline']}	{$row['HSeatrow']}

";
?>

$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

?>

After having the above foundation, we can query the database and display it

The code is as follows

Copy code

mysql_connect("localhost","root","");
mysql_select_db("cinema");
$_sql="select * from `t_hall`";
mysql_query("set names utf8");//Encoding is set to utf8
$query=mysql_query($_sql);
echo "";
echo "> ;";
while($row=mysql_fetch_array($query))
{
//Fields queried from the database
//Put the data into the html table echo "";
}
echo "

A theater number	Hall name	Seat row	Seat row
{$row['HID']}	{$row['HHall']}	{$row['HSeatline']}	{$row['HSeatrow']}

";
?>
