what php use achieve this?

thanks in advance.

in process.php file want have code looks this:

//create connection using mysqli $conn = new mysqli($servername, $username, $password, $dbname);  //prepare statement. $conn->prepare('insert tablename(fieldname) values(?)');  //put checkboxes together, if selected. $checked = ''; if(is_array($_post['voccheck'])) {     $checked = implode(',', $_post['voccheck']); }  //bind value. $conn->bind_param('s', $checked);  //execute question. $conn->execute(); 

not 100% sure need check if $_post['voccheck'] array , cant try right included on safe side. might want throw error handling in case connection doesn't work etc. useful links you:
