Well, because the way you're using htmlentities() there is ignoring
single quotes, i.e. not escaping them. Try myitem=htmlentities($myitem,
ENT_QUOTES); instead.

Also, as an aside, I think it's general acceptance to use double quotes
on HTML attributes rather than single. While that does make for
complications when the HTML is part of a double-quoted string in PHP, it
does avoid tricker problems surrounding Javascript event handlers on
code, which generally use single quotes when they are part of an HTML
attribute.
