My problem was solved no need to argue. I don't see why use a while
loop with a count variable when it produces the same result as a
foreach loop. As for using a break in the loop, I could add it but the
loop is gonna stop anyway as soon as it hits the end of the array. I
also didn't see the point in using the explode() function as long as I
remove the (in my opinion) useless index numbers from the text file
containing the username. The following code works as I expect it to:
<?php
session_start();
$users = file("../inc/users.inc.php");
if(!empty($_POST['username']) && !empty($_POST['password'])){
if(filter_var($_POST['username'],
FILTER_VALIDATE_EMAIL)){
foreach($users as $row){
$row = trim($row);
if($_POST['username'] == $row){
$_SESSION['logged_in'] = 1;
$_SESSION['username'] = $row;
}
}
if($_SESSION['logged_in'] != 1){
$error = "2";
}
}else{
$error = "4";
}
}else{
$error = "3";
}
if($error){
header("Location:");
}else{
header("Location:");
}
?>
users.inc.php:
m...@email1.com
m...@email2.com
