PHP fwrite new line
提问by Dynamiite
I'm trying to write username and password to a new line in a txt file. The output should be something like this in the txt file. I know this is not very secure but its just for learning purposes
我正在尝试将用户名和密码写入 txt 文件中的新行。txt 文件中的输出应该是这样的。我知道这不是很安全，但仅用于学习目的

This is what i have so far
这是我到目前为止
if(isset($_GET['register'])) //
{
$user = $_GET['username'];
$password=$_GET['password'];
$fh = fopen("file.txt","a+");
fwrite($fh,$user."\n"); //write to txtfile
fwrite($fh,$password."\n"); // write to txtfile
fclose($fh);
}
EDIT: Here's the solution
编辑：这是解决方案
if(isset($_POST['register'])) //
{
$user = $_POST['username'];
$password=$_POST['password'].PHP_EOL;
$fh = fopen("file.txt","a+");
fwrite($fh,$user." ".$password); //write to txtfile
fclose($fh);
}
?>

You append a newline to both the username andthe password, i.e. the output would be something like
您在用户名和密码后附加一个换行符，即输出将类似于
Sebastian
password
John

use fwrite($fh,$user." ".$password."\n");instead to have them both on one line.
Or use fputcsv()to write the data and fgetcsv()to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';
使用fwrite($fh,$user." ".$password."\n");，而不是让他们都在同一行。
或者使用fputcsv()写入数据并fgetcsv()获取它。这样你至少可以避免编码问题，例如$username='Charles, III';
...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation (use _POST instead) ;-)
...即抛开将普通密码存储在普通文件中并使用 _GET 进行此类操作（使用 _POST 代替）的所有错误；-)

How about you store it like this? Maybe in username:password format, so
你这样存放怎么样？也许是用户名：密码格式，所以
sebastion:password123
anotheruser:password321
Then you can use list($username,$password) = explode(':',file_get_contents('users.txt'));to parse the data on your end.
然后你就可以list($username,$password) = explode(':',file_get_contents('users.txt'));用来解析你端的数据了。
