Как переместиться, чтобы подогнать ответы на вопросы в массиве или как сделать sql запрос для желаемого эффекта?Я устал от этого уже несколько дней.
<code><?php
public function getQuestions()
{
$sql = 'SELECT * FROM questions';
$result = Database::query($sql);
while ($row = mysql_fetch_assoc($result)) {
$questions[] = $row;
}
return $questions;
}
public function getAnswers($qid)
{
$sql = 'SELECT idq, answer, truth FROM answers WHERE idq = '.$qid;
$result = Database::query($sql);
while ($row = mysql_fetch_assoc($result))
{
$answers[] = $row;
}
return $answers;
}
public static function array_add($a1, $a2)
{
$aRes = $a1;
foreach (array_slice(func_get_args(), 1) as $aRay)
{
foreach (array_intersect_key($aRay, $aRes) as $key => $val) $aRes[$key] += $val;
$aRes += $aRay;
}
return $aRes;
}
public static function getQuiz()
{
$db = new Database();
self::$questions = $db->getQuestions();
foreach( self::$questions as $q )
{
$qid = $q['qid'];
self::$answers[$qid] = $db->getAnswers($qid);
}
$s = Quiz::array_add(self::$questions, self::$answers);
print "<pre>";
print_r($s);
print " ";}?>
output:
Array
(
[0] => Array
(
[qid] => 1
[question] => Bunty szlachty pod has?ami obrony praw nazywamy?
)
[1] => Array
(
[qid] => 2
[question] => Kto dowodzi? wojskami kozackimi podczas powstania Chmielnickiego?
[0] => Array

)
)
Я пробовал это решение, но мне нужно иметьответы отдельно:
function get_quiz()
{
$sql = 'SELECT question, GROUP_CONCAT(answer ORDER BY answer SEPARAtoR " ") as answers
FROM questions
LEFT JOIN answers ON (questions.qid=answers.idq)
GROUP BY answers.idq;';
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result))
{
$quiz[] = $row;
}
return $quiz;
}
вывод:
Array
(
[0] => Array
(
[question] => Bunty szlachty pod has?ami obrony praw nazywamy?
[answers] => jurydyki liberum veto rokosze
)
[1] => Array
(
[question] => Kto dowodzi? wojskami kozackimi podczas powstania Chmielnickiego?
[answers] => Bohdan Chmielnicki Gustaw II Adolf Iwan IV Gro?ny
)
[2] => Array
(
[question] => W którym roku odby?a si?, morska, bitwa pod Oliw??
[answers] => 1608 1627 1654
)
