如何使用自定义动态名称创建一系列束动态变量，这些变量将随机变量存储在PHP中

发布于 2025-02-10 10:48:08 字数 10213 浏览 0 评论 0原文

该项目是一个简单的测验，用于与A vs an的基本英语语法使用（语法练习），我有一个带有问题的数组，而不是以相同的顺序显示问题，我想每次用户刷新订单该页面（为此，我创建了一个随机数的数组），但是当他们使用Get Method提交答案时，用户将看到另一个页面，其中包含与随机问题相同的动态的答案，因此我可以保存它们是一个数据库并知道用户生成以前的

的确切随机问题，这就是用户看到的

这是PHP文件，我可以看到正确的答案数量gopage_checkanswers。 php

<?php
    $user_answer1 = $_GET['ENAME_1'];
    $user_answer2 = $_GET['ENAME_2'];
    $user_answer3 = $_GET['ENAME_3'];
    $user_answer4 = $_GET['ENAME_4'];

    $value1 = $_GET['NAME_KEY_1']; 
    $value2 = $_GET['NAME_KEY_2']; 
    $value3 = $_GET['NAME_KEY_3']; 
    $value4 = $_GET['NAME_KEY_4']; 

    $totalNumberOfQuestions = $_GET['NAME_TOTAL_NUMBER_QUESTIONS'] - 1;

$totalCorrect = 0;
    
if ($user_answer1 == $value1) { $totalCorrect++; }
if ($user_answer2 == $value2) { $totalCorrect++; }
if ($user_answer3 == $value3) { $totalCorrect++; }
if ($user_answer4 == $value4) { $totalCorrect++; }
   

 ?>

<?php echo "TOTAL: $totalCorrect / $totalNumberOfQuestions"; ?>

我的问题是此代码，我想用100 $ rand_num_n变量动态填充此数组我的动物名称中的新动物单词，此$ arreglo_variables_num_azar阵列自动更新

$Arreglo_variables_num_azar = array($RAND_NUM_1,$RAND_NUM_2,$RAND_NUM_3,$RAND_NUM_4,$RAND_NUM_5);
原文

the project is a simple quiz for basic English grammar usage of A vs AN (grammar exercise for kids), I have an array with questions, instead of showing the questions in the same order, i want to shuffle the order every time the user refresh the page (for this I created an array of random numbers), but when they submit the answer with GET method, the user will see another page with the answers in the same dynamic previous order of random questions, so I can save them is a data base and know the exact random questions the user generated a previous

THIS IS WHAT THE USER SEE

<?php
    $user_answer1 = $_GET['ENAME_1'];
    $user_answer2 = $_GET['ENAME_2'];
    $user_answer3 = $_GET['ENAME_3'];
    $user_answer4 = $_GET['ENAME_4'];

    $value1 = $_GET['NAME_KEY_1']; 
    $value2 = $_GET['NAME_KEY_2']; 
    $value3 = $_GET['NAME_KEY_3']; 
    $value4 = $_GET['NAME_KEY_4']; 

    $totalNumberOfQuestions = $_GET['NAME_TOTAL_NUMBER_QUESTIONS'] - 1;

$totalCorrect = 0;
    
if ($user_answer1 == $value1) { $totalCorrect++; }
if ($user_answer2 == $value2) { $totalCorrect++; }
if ($user_answer3 == $value3) { $totalCorrect++; }
if ($user_answer4 == $value4) { $totalCorrect++; }
   

 ?>

<?php echo "TOTAL: $totalCorrect / $totalNumberOfQuestions"; ?>

这是关于如何动态使用变量名称的简化版本。

$RAND_NUM_1 = 'Hello';
$RAND_NUM_2 = 'World';
$RAND_NUM_3 = 'Foo';
$RAND_NUM_4 = 'Bar';
$RAND_NUM_5 = 'Baz';

$array = [];
for($i = 1; $i <= 5; $i++) {
    $array[] = ${"RAND_NUM_$i"};
}

print_r($array);

并将打印

Array
(
    [0] => Hello
    [1] => World
    [2] => Foo
    [3] => Bar
    [4] => Baz
)

Here is a simplified version on how to use variable names dynamically.

$RAND_NUM_1 = 'Hello';
$RAND_NUM_2 = 'World';
$RAND_NUM_3 = 'Foo';
$RAND_NUM_4 = 'Bar';
$RAND_NUM_5 = 'Baz';

$array = [];
for($i = 1; $i <= 5; $i++) {
    $array[] = ${"RAND_NUM_$i"};
}

print_r($array);

and will print

Array
(
    [0] => Hello
    [1] => World
    [2] => Foo
    [3] => Bar
    [4] => Baz
)
