The following might be slightly less confusing, and slightly more efficient:

<?php
$year = (isset($_GET['year'])) ? $_GET['year'] : 1960;

/* do some testing to make sure the value is what you want */
?>

The initial year is <?php echo $year; ?>.

Loop 10 years:

<?php
for ($i = $year, $maxYear = $year + 10;
$i < $maxYear;
++$i)
{
?>The year is now <?php echo $i; ?>.<?php
}
?>
