Why am i coding and when i run a program i get errors like "unexpected < on line for example 2 and on the line there is <form>

Question

Which kind of error is this?

Answer 1

According to the php code in your profile, you must close the php tag before writting html to output as is:

<?php
// php code
?> <!-- here's the php closing tag, and now start static html -->
<input ...>

Answer 2

Maybe the error is on the line before that. Check what is before the error. Maybe you forgot to end something.
