有数组如下:
- PHP code
//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
