PHP in_array issue

so im messing around with some php and for some reason in_array() won't pickup if something is within the array, correctly?

index.php:

<form action="login.php" method="get">
    <input name="username" type="text" />
    <input name="password" type="password" />
    <input id="submit" type="submit" />
</form>

login.php:

    <?php
    $username = $_GET["username"];
    $password = $_GET["password"];
        include('data/user_data.php');
        if(in_array($username, $users)):
            echo "in array";
        else: echo "not in array";
        endif;

?>

user_data.php:

<?php $users = array(
dextermb => array("dextermb", "password"),
tonymb => array("tonymb", "password2")
)
?>

When inputting "dextermb" or "tonymb" into username and submitting I get the result "not in array" even though it is in the array?

Thoughts on what might be the issue?

Simply You can use a php built in function 

     if(array_key_exists($username, $users)){
     echo "in array";
     }else{
          echo "not in array";
     }

If this is your users array:

$users = array(
    'dextermb' => array("dextermb", "password"),
    'tonymb' => array("tonymb", "password2")
);

Then you want to simply do:

if(isset($users[$username])) {

Or alternatively:

if(array_key_exists($username, $users)) {

The username is the key in your $users array, the in_array method looks for values (and not nested values).
