I'm not sure about the title text because I don't know what I have to ask! If you know a better title please fix it!
Recently I making a login system with php but I have a question.
I have this code:
$result = mysqli_query($con,"SELECT * FROM login_info WHERE email='$email_send'");
$email_send is the email that form post to my page.
Here is my question how can I understand that email that post is exist in the login_info database?
