My gut tells me wrapping esc_attr() in intval() is redundant when it comes to escaping input, but I would like to double-check.

Also: considering that `<option value="">- select no. -</option>` is hardcoded/value is null, that chunk of input wouldn't need to be escaped, correct?

Here is my current code set-up:

    		<select name="_number">
			<option value="">- select no. -</option>
				<?php
				$savedNo = intval( get_post_meta( $post->ID, '_number', true ) );
				for ($x = 1; $x <= 100; $x++) {
					echo '<option value="'
						. intval(esc_attr($x)) . '"'
						. ($x === $savedNo ? ' selected="selected"' : '' )
						. '>'
						. 'No. ' . intval(esc_attr($x))
					. '</option>';
				}
				?>
			</select>


Thank you!
