从服务器中获取用户所有信息(SQL SELECT语句)并以表格形式出现
<?php

if (!$con)
die(\'Could not connect: \' . mysql_error());
mysql_select_db("test", $con);
mysql_query("DELETE FROM user WHERE username = \'$_POST[username]\'");
mysql_close($con);
?>
删除该用户所有信息delete.php
<?php
$con = mysql_connect("localhost:3306","root","");
if (!$con)
die(\'Could not connect: \' . mysql_error());
mysql_select_db("test", $con);
$sql = "INSERT INTO user (username,password)
VALUES
(\'$_POST[username]\',\'$_POST[password]\')";
if (!mysql_query($sql,$con))
die(\'Error: \' . mysql_error());
echo "1 record added";
mysql_close($con);
?>
注册一个新用户insert.php
<?php
$con = mysql_connect("localhost","root","");
if (!$con)

mysql_close($con);
?>
