1. PHP网址 URL拼接

$_SERVER['QUERY_STRING'] 获取获取当前url的所有querystring

parse_str and http_build_query:

parse_str($queryString, $params);

foreach ($params as $key => $term)

$these = array_diff_assoc($params, array($key => $term));

printf("%s
\n", http_build_query($these), $term);

Example output:

a

b

c

参考 http://stackoverflow.com/questions/8609163/php-retrieve-keys-from-query-string-for-each-key-create-url-removing-that-key

2.php 获取当前url

$url_this = "http://".$_SERVER ['HTTP_HOST'].$_SERVER['PHP_SELF'];

3.strtotime("-1 week"), strtotime("-n days");可以很方便的获取当前日期的前n天、周、月的时间戳
