$i++ should be INSIDE the while loop to have effect. Now you don't increase
it so it keeps writing the same form over an over again because $i gets no
bigger and therefore it's always less than 60 thus it becomes an infinite
loop.
fix
<?
} // Loop stops here, $i is never reached.
$i++;
?>
to
<?
$i++; // Now it's inside the loop and is incremented
}
?>
Or even better, use a for-loop instead. That way you'll do all the necessary
loop-control in one logical place:
for($i=0; $i<=60; $i++) { ....
