php 運算元組有關問題

php 運算元組問題
有數組如下：

PHP code

//以下是列印出的結果$html = array('2012-05-02'=>1,'2012-05-07'=>1,'2012-05-24'=>2,'2012-05-25'=>2,'2012-05-28'=>3);print_r($html);//Array ( [2012-05-02] => 1 [2012-05-07] => 1 [2012-05-24] => 2 [2012-05-25] => 2 [2012-05-28] => 3 ) 

想得到如下的結果,
數組個數為當月的天數date('t',time())，如果上面$html中有的,則用上面的數組，沒有的則添0

如下、

PHP code

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 )

謝謝

PHP code

$html = array('2012-05-02'=>1,'2012-05-07'=>1,'2012-05-24'=>2,'2012-05-25'=>2,'2012-05-28'=>3);$ar_tmp = range(1, date('t'));$ar = array();foreach($ar_tmp as $v) $ar[date('Y-m-').str_pad($v, 2, '0', STR_PAD_LEFT)] = 0;print_r(array_merge($ar, $html));
