PHP - Stdin/stdout Password

I've been doing some limited PHP coding for a while, but never really had any training, just learned by searching for specific needs.  So I decided to get a book and start from the beginning to see what else PHP can do that I don't know about.

Problem is that I can't even get past the first simple program in the book.  I'm just supposed to take input from the user and save it to a variable with this line of code:

Code: [Select]
$name = fgets(STDIN);
But when I access that page on my webserver, I get this error:

Warning: fgets() expects parameter 1 to be resource, string given in /Users/username/Sites/sitename/index.php

There's got to be something simple I'm missing, since this is the easiest task in the book.    Any help is appreciated.  Thanks!

Hello PhP Freaks forum
In the past weeks ive been trying to make a website, where you can register. Everything seems to work except my cherished Change password feature. Everytime you try to change the password, it just resets it to nothing.

Here is the code below.

<?php
         if(isset($_SESSION['username']))
         {
            $username = $_SESSION['username'];
            $lastname = $_SESSION['lastname'];
            $firstname = $_SESSION['firstname'];
            $email = $_SESSION['email'];
               
            echo "
            
               <h4>Options for:</h4> &nbsp; $username
               <br />
               <br />
               First name: &nbsp; $firstname
            
               <br />Last name: &nbsp; $lastname       
   
   <br /><br /><h3>Want to change your password:</h3><br />
   
      <form action='?do=option' method='post'>
   
      Old password <input type='password' placeholder='Has to be between 5-15 digits' name='password' size='30' value='' /><br />
                  <br />
      New Password<input type='password' placeholder='Has to be between 5-15 digits' name='newpass' size='30' value='' /><br />
                  <br />
      Confirm new password <input type='password' placeholder='Has to be between 5-15 digits' name='passconf' size='30' value='' /><br />
                  
      <center></div><input type='submit' value='Submit'/></center></form>";   
      
            
         }else{
            echo 'Please login to view your options!';
         }
      
      $password = $_REQUEST['password'];
      $pass_conf = $_REQUEST['newpass'];
      $email = $_REQUEST['passconf'];
      
      $connect = mysql_connect("Host", "User", "Password");
      if(!$connect){
      die(mysql_error());
      }
      
      //Selecting database
      $select_db = mysql_select_db("My Database", $connect);
      if(!$select_db){
      die(mysql_error());
      }
      
      //Find if entered data is correct
      
      $result = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'");
      $row = mysql_fetch_array($result);
      $id = $row['id'];

            
         mysql_query("UPDATE users SET password='$newpass' WHERE username='$user'")
      
      ?>          

And i do know that i dont have a

if(Empty($newpass)){
Die(Please fill out the new password)                                                 
}

Or any security on the others, but the problem just seems that it resets the password into nothing

Hope i can get this fixed

Best Regards

William Pfaffe

Hi Friends ....
I encrypt user password by SHA('$Password') method but now i want to add "Forget Password Module" for which I need to decrypt it first before tell my user but I don't Know how to decrypt it.
Please help me........

I am having some trouble getting this to pull the password correctly from the database.
I believe the problem is from the password being in md5 format.
I am not sure how to fix the issue.

Much thanks
