PHP猜字游戏有问题吗 猜猜单词游戏

现在我需要使用一个循环来遍历数组，以查看猜测的字母是否在单词中

我还想告诉用户该字母出现了多少次

。。。并用实际字母更新单词的蒙面版本

---

这里需要注意的是，当您通过隐藏的输入字段跟踪猜测计数时，您并没有跟踪以前的猜测。我建议您使用一个隐藏的输入字段来存储以前的猜测

在页面顶部：

// get your random word
$random = array_rand($words);
$selected_word = $words[$random];

// set up temporary array to store output letters or *
$output = array();
// split word into each letter
$letters = str_split($selected_word);

foreach($letters as $letter) {
    // if the letter was guessed correctly, add it to the output array, 
    // otherwise add a *
    $output[] = ($letter == $guess) ? $letter : '*';
}

// output the results (implode joins array values together)
echo implode($output);

然后再往下走：

$count = 0;
$guesses = array();
if(isset($_POST['guesses']))
    $guesses = explode('|', $_POST['guesses']);

if(isset($_POST['submit'])) {
    $guess = trim(strtolower($_POST['guess']));
    if(!in_array($guess, $guesses))
        $guesses[] = $guess;

    $count = isset($_POST['count']) ? (int) $_POST['count'] : 0;
    $count++;
}

您的

$count

未初始化

$number_of_occurences = substr_count($selected_word, $guess);

// get your random word
$random = array_rand($words);
$selected_word = $words[$random];

// set up temporary array to store output letters or *
$output = array();
// split word into each letter
$letters = str_split($selected_word);

foreach($letters as $letter) {
    // if the letter was guessed correctly, add it to the output array, 
    // otherwise add a *
    $output[] = ($letter == $guess) ? $letter : '*';
}

// output the results (implode joins array values together)
echo implode($output);

$count = 0;
$guesses = array();
if(isset($_POST['guesses']))
    $guesses = explode('|', $_POST['guesses']);

if(isset($_POST['submit'])) {
    $guess = trim(strtolower($_POST['guess']));
    if(!in_array($guess, $guesses))
        $guesses[] = $guess;

    $count = isset($_POST['count']) ? (int) $_POST['count'] : 0;
    $count++;
}

<input type="hidden" name="guesses" id="guesses" value="<?=implode('|', $guesses)?>">

foreach($letters as $letter) {
    // if the current letter has already been guessed, add it to 
    // the output array, otherwise add a *
    $output[] = in_array($letter, $guesses) ? $letter : '*';
}
