Question

我有一个while循环获取一行，我正在尝试创建一个结构，以便每行创建2个链接。第一个是德语单词，第二个是英语单词。我得到的输出重复，好像行没有增加。我把它缩小到了这个范围：

PHP：

while ($row = $database->row()->fetch()) {
    foreach ($row as $value) {
        $this->data .= $value . "!";
    }
    list($this->pid, $this->german, $this->english) = explode("!", $this->data);
    $this->links .= "<a href=\"#\" class=\"german $this->pid\">$this->german</a><br/><a href=\"#\" class=\"english $this->pid\">$this->english</a><br/>";
}

输出：

die Männer
men
die Männer
men

Answer 1

    $row = array();
    while ($row = $database->row()->fetch()) {
        $row[] = $row;
    }

    foreach ($row as $value)
    {
        $this->data .= $value . "!";
        list($this->pid, $this->german, $this->english) = explode("!", $this->data);
        $this->links .= "<a href=\"#\" class=\"german $this->pid\">$this->german</a><br/><a href=\"#\" class=\"english $this->pid\">$this->english</a><br/>";
    }

Answer 2

我通过查看键并基于简单的匹配字符串测试创建变量来解决问题。如果有人能改进我的答案，我想听听。感谢。

PHP：

while ($row = $database->row()->fetch()) {
    while(list($key, $value) = each($row)) {
        if ($key == "PID") {
            $this->pid = $value;
        }
        if ($key == "german") {
            $this->german = $value;
        }
        if ($key == "english") {
            $this->english = $value;
        }
    }
    $this->links .= "<a href=\"#\" class=\"german $this->pid\">$this->german</a><br/><a href=\"#\" class=\"english $this->pid\">$this->english</a><br/>";
}

PHP重复输出
