Uncaught Error: Call to undefined function

Hi everyone, i am currently making a login/registration system and i'm making a send_email function so the user can recover their password.

The code is:

function recover_password() {

if($_SERVER['REQUEST_METHOD'] == "POST") {

    if(isset($_SESSION['token']) && $_POST['token'] === $_SESSION['token']) {

          $email = $_POST['email'];

          if(email_exists($email)) {

              $validation = md5($email, microtime());

              $subject = "Please reset your password";

              $message = "Hi here is your password reset code: {$validation}

              Click here to reset your password http://localhost/login/code.php?email=$email&code=$code

               ";

              $headers = "From: noreply@zestymemes.com";

              send_email($email, $subject, $message, $headers);

          }

     }

  }

Now the error i'm getting when i'm posting the submission to send me the email is:

Fatal error: Uncaught Error: Call to undefined function email_exists() in /Applications/XAMPP/xamppfiles/htdocs/login/functions/functions.php:424 Stack trace: #0 /Applications/XAMPP/xamppfiles/htdocs/login/recover.php(11): recover_password() #1 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/login/functions/functions.php on line 424

I searched around but with no help really. What could i have done wrong? The weird thing is longer up in my code i use the email_exists() and that works totally fine, but not this code.

either your function is out of scope or it has not been created

andi . the email_exists function has been created as i'm using it longer up in my code.

meaning that the email_exists() function could be within a different class. read more about scope here (http://stackoverflow.com/questions/5955446/php-function-scope)
