我在 index.php 页面的中途有以下 HTML:
<form action="" method="post"><input type="submit" value="Reset Game" class="reset-button" title="Admitting defeat?"></form>
在我的页面顶部,我有以下检查:
if (isset($_POST["submit"]) {
    if ($_POST["submit"] === "Reset Game"] {
        $_SESSION["word"] = generate_word("dictionary.txt");
        $_SESSION["word-progress"] = turn_to_underscores($_SESSION["word"]);
    }
}
它为我的刽子手游戏生成了单词,以及带下划线的版本。以下是这些功能:
    /**
     * Generate a random word from the given dictionary file
     * @param $filename Name of the dictionary file
     * @return Random word
     */
    function generate_word($filename) {
        $dictionary_file = new SplFileObject($filename);
        $dictionary_file->seek(rand(0, 80367));
        return trim($dictionary_file->current());
    }
    /**
     * Accepts a word and returns it as underscores for obfuscation
     * @param $word A given word
     * @return Returns the word as underscores
     */
    function turn_to_underscores($word) {
        $underscored_word = "";
        for ($i = 0; $i < strlen($word); $i++) {
            $underscored_word .= "_";
        }
        return $underscored_word;
    }
我打电话带来的require "functions.php";。
我到底做错了什么?
