Php array operations

Php operation array problems include the following arrays: PHPcode below is the output result $ htmlarray (& gt;-05-07 & gt;-05-24 & gt; 2,2012-05-25 & gt; 2,2012-05-28 & gt; 3); print_r ($ html); Array ([20 php operation Array problem
An array is as follows:

PHP code

  // The following is the printed result $ html = array ('2017-05-02 '=> 1, '2017-05-07' => 1, '2017-05-24 '=> 2, '2017-05-25 '=> 2, '2017-05-28' => 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)

To get the following results,
The number of arrays is the number of days in the current month date ('t', time (). if there is one in $ html above, the above array is used, and 0 is added if there is none.

As follows,

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 )

Thank you.
