Question

基本上我试图用0,100之间的2个随机变量显示数学方程式。我需要存储2个不同的变量：正确的问题数量和回答的总问题。仅通过一次显示一个问题并在提交时，提示用户是否要继续回答问题，或者如果继续则停止然后刷新随机值。在停止显示3个存储的变量时。格式为“”正确和“”回答的总问题。

    <?php
    function displayQuestion(){
    $firstVal = rand(0,100);
        $secondVal = rand(0,100);
        $valTotal = $firstVal + $secondVal;
    echo $firstVal . "+" . $secondVal . "=";
    }

    function answersCorrect(){
         $answer = 0;

         $firstVal = rand(0,100);
             $secondVal = rand(0,100);
             $valTotal = $firstVal + $secondVal;
         do {$valTotal;
         $answer ++;
         function displayAnswer() {
         if ($answer == $valTotal){
             $correct ++;
             $answer ++;        
         }
         echo "<p>You got {$correct} answers correct out of {$answer}.</p>";
     }
         }

         while ($answer == $valTotal);
         $correct = 0;

PHP使用多个数学方程生成器来获得总体结果
