所以这是我非常简单和基本的帐户系统(只是一个学校项目),我希望用户能够更改他们的密码.但我不确定如何在一行中替换密码值,保持所有其他值相同.

CSV文件:

ID,Username,Email,DateJoined,Password,UserScore,profilePics
1,Test,Test@Test.com,03/12/2014,Test,10,uploads/profilePics/Test.jpg
2,Alfie,Alfie@test.com,05/12/2014,1234,136,uploads/profilePics/Alfie.png

PHP :("cNewPassword"=确认新密码)

<?php
session_start();
if(empty($_POST['oldPassword']) ||  empty($_POST['newPassword']) || empty($_POST['cNewPassword'])) {
    die("ERROR|Please fill out all of the fields.");
} else {
    if($_POST['newPassword'] == $_POST['cNewPassword']) {
        if ($_POST['oldPassword'] == $_SESSION['password']) {

            $file = "Database/Users.csv";
            $fh = fopen($file, "w");
            while(! feof($file)) {
                $rows = fgetcsv($file);
                if ($rows[4] == $_POST['oldPassword'] && $rows[1] == $_SESSION['username']) {
                    //Replace line here
                    echo("SUCCESS|Password changed!");
                } 
            }
            fclose($file);
        }
        die("ERROR|Your current password is not correct!");
    }
    die("ERROR|New passwords do not match!");
}
?>
