php 操作数组有关问题

php 操作数组问题
有数组如下：

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->//以下是打印出的结果$html = array('2012-05-02'=>1,'2012-05-07'=>1,'2012-05-24'=>2,'2012-05-25'=>2,'2012-05-28'=>3);print_r($html);//Array ( [2012-05-02] => 1 [2012-05-07] => 1 [2012-05-24] => 2 [2012-05-25] => 2 [2012-05-28] => 3 ) 

想得到如下的结果,
数组个数为当月的天数date('t',time())，如果上面$html中有的,则用上面的数组，没有的则添0

如下、

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Array ( [2012-05-01]=>0 [2012-05-02] => 1 [2012-05-03]=>0 [2012-05-04]=>0 ... [2012-05-07] => 1 ... [2012-05-24] => 2 [2012-05-25] => 2 [2012-05-28] => 3 )

谢谢
