Parsing Extjs and PHP data interaction (adding, deleting, checking and modifying)_PHP tutorial

Copy code The code is as follows:

//The search is not done yet, the data is out, but it cannot be displayed

Index.php file



Copy code

The code is as follows:

header("Content:text/html;charset=utf-8");
$link = mysql_connect("localhost","root","123456")or die('error'.mysql_error());
mysql_select_db("stu",$link);
mysql_query('set names utf8');
$sql = "select count(*) num from men";
$num = mysql_query($sql);
$count = mysql_fetch_array($num);
$start = $_POST['start'];
$limit = $_POST['limit'];
$sql2 = "SELECT * FROM men limit {$start},{$limit}";
/*
if (!$_POST)
{
 $sql2 = "SELECT * FROM member";
} else {
 $sql2 = "select * from member limit {$start},{$limit}";
}
*/
$data = array();
$result = mysql_query($sql2);
while(!!$info = mysql_fetch_array($result,MYSQL_ASSOC))
{
 $data[] = $info;
}
//$j = json_encode($data);
$j = "{totalProperty:100,root:".json_encode($data)."}";
echo $j;
?>

Add.php文件如下：

复制代码 代码如下:

header("Content:text/html;charset=utf-8");
$link = mysql_connect("localhost","root","123456")or die('error'.mysql_error());
mysql_select_db("stu",$link);
mysql_query('set names utf8');
$name = $_POST['username'];
$pwd = $_POST['password'];
$time = $_POST['regTime'];
$email = $_POST['email'];
/*
$name = 'aaaa';
$pwd = 'aaaa';
$time = '2011-12-31';
$email = 'aaaa';*/
$sql = "INSERT INTO men (username,password,regTime,email) VALUES ('{$name}','{$pwd}','{$time}','{$email}')";
//mysql_query($sql)
if (mysql_query($sql))
{
 echo 'ok';
}
?>

Del.php文件如下：

复制代码 代码如下:

header("Content:text/html;charset=utf-8");
$link = mysql_connect("localhost","root","123456")or die('error'.mysql_error());
mysql_select_db("stu",$link);
mysql_query('set names utf8');
$id = $_POST['id'];
$sql = "DELETE FROM men WHERE id={$id}";
if (mysql_query($sql))
{
 echo 1;
} else {
 echo 0;
}
?>

数据库文件men.sql
数据库名叫：stu
表名为：men
可以把下面的复制到一个文本文档里，然后新建stu数据库，导入就可以。
