Why you should use & instead of &
choose a link:
- lousy coding:
-
href="amp.php?id=1£=2¢=3®=4°=5"=6©=7<=8§=9¥=10«=11»=12>=13"
- proper coding:
-
href="amp.php?id=1&pound=2&cent=3&reg=4&deg=5&quot=6&copy=7&lt=8&sect=9&yen=10&laquo=11&raquo=12&gt=13"
This is an illustration for Who cares about ampersands. Note, that despite unencoded ampersands in the first link this pages is still valid.
