echo function is not showing any output

Question

<?php
session_start();

if (isset($_POST["user_name"]) && isset($_POST["user_pwd"])) {
    include"php/connect_to_mysql.php";
    $user_name = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["user_name"]);
    $user_pwd = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["user_pwd"]);

    $sql = "SELECT * FROM user_ac WHERE user='$user_name' OR email='$user_name' AND pwd='$user_pwd' LIMIT 1";
    $result = mysqli_query($myConnection, $sql);

    if (mysqli_num_rows($result) > 0) {
        echo "Successfully Logged In";
        header("location: login.html?abc=234");
    } else {

    }
} else {

}

In this code, inside the second if statement, echo is not displaying anything, but the header function executes correctly.

Please help, thanks.

header function redirect you to new page, so your echo will appear in your current page but your code by this line:

header("location: login.html?abc=234");

will redirect you to new page.

You cannot see the echo because you are going to another page.

As test, remove the header("location: login.html?abc=234"); and you will see the echo.
