php 如何把一条sql语句写入数据库

?php

$dbhost = 'localhost:3306'; // mysql服务器主机地址

$dbuser = 'root'; // mysql用户名

$dbpass = '123456'; // mysql用户名密码

$conn = mysqli_connect($dbhost, $dbuser, $dbpass);

if(! $conn ){

die('连接失败: ' . mysqli_error($conn))

;}

echo '连接成功br /'; // 设置编码，防止中文乱码mysqli_query($conn , "set names utf8");

$runoob_title = '学习 Python';

$runoob_author = 'RUNOOB.COM';

$submission_date = '2016-03-06';

$sql = "INSERT INTO runoob_tbl ".

"(runoob_title,runoob_author, submission_date) ".

"VALUES ".

"('$runoob_title','$runoob_author','$submission_date')";

mysqli_select_db( $conn, 'RUNOOB' );$retval = mysqli_query( $conn, $sql );

if(! $retval ){

die('无法插入数据: ' . mysqli_error($conn))

;}

echo "数据插入成功\n";

mysqli_close($conn);

?

按照步骤开始，多看PHP手册。

php中使用sql语句写入数据，怎样在$_POST['ID']插入一个变量

改成{$_POST['Region'.$jc]},

原先的{$_POST['Region".$jc."']}，{}里的“”是相对独立的，不合外面的“”配对，也就是说“”就是单引号包含的一串字符串中的字符，所以，显而易见的PHP不会对".$jc."做concat处理，只是作为一串字符。
