pregmatch is not working PHP -


i have piece of code

if(preg_match('/zwi[a-za-z0-9]+tch/', $cust_ref_no)) {             echo "im in";         }

i have $cust_ref_no 'zwijdgc83806161tch'

this not working.any guess why?

the regex fine. $cust_ref_no must not think is, try echoing prior preg_match.

regex test: http://regexpal.com/?flags=g&regex=zwi%5ba-za-z0-9%5d%2btch&input=zwijdgc83806161tch

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
