hi everyone i need help in my query while user login.

<?php

$username = $_POST["username"];
$password = $_POST["password"];

$con = oci_connect("user","pswrd","db");
if(! $con)
{
    die('Connection Failed'.oci_error());
}
$query = "SELECT username, password FROM users
WHERE username=$username";

$stmt = oci_parse($conn, $query);

$row = oci_fetch_array($stmt, OCI_NUM);;

if($row["username"]==$username && $row["password"]==$password)
    echo"You are a validated user.";
else
    echo"Sorry, your credentials are not valid, Please try again.";
?>

kindly guide me in my code why its not working?

  1. For starters are you sure you can break lines 11 and 12?
  2. Where is the OCI execute?
    Example at http://php.net/manual/en/function.oci-fetch-array.php

  3. How are you going to avoid breaking one of the cardinal rules about passwords?

It's rather scary what I see folk code today.

no sir explain in which line i need to change to a perfect code

Sorry, I've yet to see perfect code. But I did try to share why your system is broken in both a missing line plus why it's a bad idea to store passwords.

I can only guess you didn't check the example in the PHP document link I shared.
