check if user input exist in database using php and mongodb

I want to check first if the email exists then check the password but
I only want to use PHP and MongoDB not any other language or tool
because I’m just a beginner.

when I enter an input the page change to an empty page and nothing
happen. I know my error is from the line of the array $findemail and
downward.

am I using the $cursor in the right way and if so am I accessing the
$findemail in the right way using $d[’email’] to compare it with
$email

//Select a database

$email = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_STRING);
$password = filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);



$findemail = [
"email" => $email,
"password" => $password
 ];
 

$cursor = $db->$collection->find($findemail);

foreach ($cursor as $d ){

if($d['email'] == $email and $d['passwprd'] == $password){   
    echo "success";
 }
else {
    echo "fail";
}
    }

>Solution :

Try to this:

$cursor = $collection->findOne($findemail);

if($cursor){
    if($cursor->email == $email and $cursor->password == $password){   
        echo "success";
    }
}
