How to convert back QImage to cv::Mat?

How do I convert a dash-delimited string to a PHP namespace format?

• I need to convert "system/common/pdf-logger" to "System\Common\PdfLogger", which involves a 2 step preg_replace( ). First i'll need to convert all backslashes (/) to forward slashes, and convert the following character to an uppercase (so "system/common/pdf-logger" would become "System\Common\Pdf-logger"). Then I'll need to remove all dashes and convert the following character to an uppercase (so that "System\Common\Pdf-logger" would become "System\Common\PdfLogger"). How do I do that with just one preg_replace( ) call? I can do that with two, but it'll be really nice if I can perform both evaluations in one go.

  Well here's a one line function that does it for you, not pretty but works good :) function create_namespace ($string) { return str_replace (" ", "", str_replace ("/", "\\", ucwords (str_replace ('-', ' ', str_replace ('/ ', '/', ucwords (str_replace ('/', '/ ', $string))))))); }$str = "system/common/pdf-logger";echo create_namespace ($str);
