// Collect the OSC code sharing list, with the title linked to the Author

$ Rang = ". code_list li ";
$ Hj = new QueryList ($ url, $ reg, $ rang );
$ Arr = $ hj-> jsonArr;
Print_r ($ arr );
// If you want to obtain the top 40 active contributor images on the right of the current page and obtain JSON data, you can write
$ Reg = array ("portrait" => array (". hot_top img", "src "));
$ Hj-> setQuery ($ reg );
$ Json = $ hj-> getJSON ();
Echo $ json ."

// Obtain the content on the OSC content page
