javascript - How should I use PHP $_GET and variables to fill my template page with content from other files? -


i'm new php , web development, , i'm trying figure out how design site little copy-and-pasted code possible. essentially, want each page use same layout, header menu, , footer; difference between each page stuff inside 'content_container'. simplified version of i'm working right now: 

<?php $content = htmlspecialchars($_get["content_url"]);?>  <body>     <div id="main_container">         <?php require 'header.html';?>          <div id="content_container">             <?php include $content;?>         </div>          <?php require 'header.html';?>     </div> </body>

all of site's 'content' stored in pages (about.html, social.html, etc.) should somehow loaded 'content_container' div of index.php 'template' page. way, should easy maintain , update site's content without touching template @ all. before this, tried using ajax load in content asynchronously wasn't able link directly individual pages through method, using php $_get seems better option.

i have idea of want do, unfamiliarity web development , syntax of php kind of roadblock me right now. so, how can use php $_get populate page content file? edit 1: or, going problem wrong way, , should doing instead?

edit 2: mere sake of learning, i'd kind of prefer see how kind of thing done using php (or js, if possible). know there lots of template libraries/frameworks out there, want understand how implement these kind of things on own if can.

so if understand you sending url variable this: http://www.yoursite.com/?content_url=http://www.yoursite.com/pages/about.html , plan want fetch url of file located, , include files contents current page.

i think missunderstand how people commonly use variables, , recommend not proceed in way doing it. bad several reasons. it's bad load content ajax, because google not able index content.

now answer: if still want use $_get load content page. this:

example url: http://www.yoursite.com/?page=about

php code:

<?php     //check if variable "page" set "about", load about.html     if($_get['page'] == "about"){         $content = file_get_contents("http://www.yoursite.com/pages/about.html");     } ?>

you can read file_get_contents here http://php.net/file_get_contents

please note not "best" way solve urls websites. answer of how can achieve asking for. if want more advanced solution should mod_rewrite , .htaccess.

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;...
