esc_html
and esc_attr
are near-identical, the only difference is that output gets passed through differently named filters ( esc_html
and attribute_escape
respectively).
esc_url
is more complex and specific, it deals with characters that can’t be in URLs and allowed protocols (list of which can be passed as second argument). It will also prepend input with http://
protocol if it’s not present (and link is not relative).
