PHP array_count_values returning an empty array -


Maybe I'm seeing something very obvious but this code does not work: 

  & Lt; Pre & gt; & Lt ;? Php print_r (($ progress)); ? & Gt; & Lt ;? Php print_r (array_count_values ​​($ progress)); ? & Gt; & Lt; / Pre & gt;

Outlook is: 

  array ([0] => 1 [1] => 1 [2] = & gt; 1 [3] => 1 [4] => 1 [5] => 1 [6] => 1) Array ()

What's here That's wrong? Why is empty_count_values ​​returning an empty array?

array_count_values ​​ works with only / Code> and integer values ​​my guess: you're accumulating booleans inside $ progress . You can put them at int before adding them to $ progress .

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
