使用Xampp的php MySQL连接错误
[英]Error in php mysql connection using xampp
问题描述
I'm trying to connect a HTML page using PHP form to MySQL database using Xampp. 
我正在尝试使用Xampp将使用PHP表单的HTML页面连接到MySQL数据库。 The HTML page is working fine but as soon as I press submit button a page with distinct characters appears, can anybody help with the problem?![php page][1] HTML页面运行良好，但是当我按下“提交”按钮时，会出现一个包含不同字符的页面，有人可以帮助解决该问题吗？！[php页面] [1]

在这里，让我更正语法：
$sql="INSERT INTO exp VALUES('".$_POST['fnm']."','".$_POST['lnm']."','".$_POST['mob']."', '".$_POST['age']."','".$_POST['src']."','".$_POST['des']."','".$_POST['str']."','".$_POST['area']."', '".$_POST['cty']."')";

this code is wrong : $sql="INSERT INTO exp VALUES('$_POST[fnm]', '$_POST[lnm]', $_POST[mob], $_POST[age], '$_POST[src]', '$_POST[des]', '$_POST[str]', '$_POST[area]', '$_POST[cty]')"; 此代码是错误的： $sql="INSERT INTO exp VALUES('$_POST[fnm]', '$_POST[lnm]', $_POST[mob], $_POST[age], '$_POST[src]', '$_POST[des]', '$_POST[str]', '$_POST[area]', '$_POST[cty]')";
as you are not referring $_POST variables using their name , missing the quotes surrounding the variable name . 因为您没有$_POST variables using their name 引用 $_POST variables using their name ，所以缺少了变量名周围的引号 。 correct the line and your data should be inserting successfully. 更正该行，您的数据应成功插入。

Try using the following PHP and let us know what happens: 尝试使用以下PHP，让我们知道会发生什么：
$sql="INSERT INTO `exp` VALUES('{$_POST['fnm']}', '{$_POST['lnm']}',
'{$_POST['mob']}', '{$_POST['age']}', '{$_POST['src']}', '{$_POST['des']}',
'{$_POST['str']}', '{$_POST['area']}', '{$_POST['cty']')"
or die('Error: ' . mysqli_error($con));
$output = $con->$sql
echo "1 record added";
mysqli_close($con);
Is anything different this way? 这样有什么不同吗？
Note: To be syntactically proper you would want to explicitly state where you want the values inserted as follows: 注意：为了在语法上正确，您需要明确声明要插入值的位置，如下所示：
$sql="INSERT INTO `table_name` (`first_value`, `second_value`, `third_value`)
VALUES ('{value1}', '{value2}', '{value3}');";

I know it's way too late guys, but I solved the issue. 我知道这太迟了，但是我解决了这个问题。 This doesn't means it took me 3 years to solve it, I just forgot to post the answer. 这并不意味着我花了3年的时间来解决它，我只是忘记发布答案了。 It was happening because I was editing the php code in Wordpad. 发生这种情况是因为我正在Wordpad中编辑php代码。 I copied and saved the code in Notepad and the issue was solved. 我将代码复制并保存在记事本中，此问题已解决。
Thank you for your valuable input guys. 感谢您的宝贵意见。
