I can not understand why the $colvo_prav variable $colvo_prav not increase by 1, but displays a bunch of numbers? That is, it is necessary that for every true in the if construct, the $colvo_prav variable is incremented by one. And if if false , then, accordingly, no

 for($i = 1; $i <= 25; $i++) { $cookie_t = $_COOKIE["otveti".$i]; $DB->query = "SELECT correct_answer FROM test3 WHERE id=".$i; $correct_answer = $DB->read('correct_answer'); if($cookie_t != '') { $DB->query = "SELECT answer".$cookie_t." as otv FROM test3 WHERE id=".$i; $vash_otv = $DB->read('otv'); } $colvo_prav = 0; if($correct_answer == $vash_otv){ $colvo_prav++; $verno = "Правильно!"; }else $verno = "Неправильно. Правильный ответ:".$correct_answer; $DB->query = "SELECT question FROM test3 WHERE id=".$i; $question = $DB->read('question'); $otveti_na_voprosy = "Вопрос №".$i.": ".$question."\nВаш ответ:".$vash_otv." ".$verno."\n\n"; echo $colvo_prav;

    The answer is simple. you counter constantly reset. $colvo_prav = 0 must be before the cycle begins - Alexey Shimansky

    before the beginning of the CYCLE , not the terms)) ... before for (... - Alexey Shimansky

    Well, write echo $colvo_prav already after the cycle and that's it ..... and this is how (echo) is now called up every iteration inside the cycle ... that's why cadabra adabra is Alexei Shimansky

    Sobssn, when I told you $colvo_prav = 0 должен находится до начала цикла did you really leave $colvo_prav also in the cycle? - Alexey Shimansky
