How to substract numbers within a string in PHP? -


Say a string variable containing data data, say $ x = "OP / 12 / DIR"; The status of the number data can be changed in any case by changing the user's application to the will of the user, and slash bar can be replaced by any other character; But number data is mandatory. So what's the way to extract the number data from the string?

Change everything that is empty with no space string.

$ numbers = preg_replace ('/ [^ 0-9] * /', '', $ x);

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.
