Answer 3

Try this:
<?php if( isset($_GET['k']) && !empty( $_GET['k'] ) ){ echo $_GET['k'];} ?>

This way, if k parameter is not mentioned in your url, the input's value will be empty otherwise it'll take the value of ?k=something.

optionally, use echo htmlspecialchars($_GET['k']); for extra security.
