Question

I have this php code:

$flag = 0;
$f = fopen("1.txt", "r");
while (!feof($f))
{
    $a = fgets($f);
    $b = explode(",", $a);
    if ($_POST['username'] == $b[0]&& $_POST['password'] == $b[1])
    {
        $flag = 1;
        echo ("Correct");
        break;
    }
}
 if ($flag == 0)
     echo ("Incorrect");
fclose($f);

and 1.txt file is this:

1,1
2,2
3,3
4,4
5,5

I send data to my php page that have just this code but I always get Incorrect. I don’t know why if doesn’t work!(I checked the $_POST['username'] and $_POST['password'] but all were correct!) can anybody help me?

Answer 1

You may need to trim($b[1]) because it probably reads the new line into the string so $b[1] would never be equal.

Edit:

Actually, you should just replace $a = fgets($f); with $a = trim(fgets($f));
