Question

我试图找到最合乎逻辑（一如既往）的方式来接受查询中的WHERE参数列表。我遇到了一个常见的问题，即如何确定它是否是数组的结尾，我需要添加或不添加另一个＆＃34; AND＆＃34;

$params = array(
   array("id","=","1"),
   array("id","!=","2"),
   array("name","=","test"),
)

someQuery($params);

private function someQuery($where = null){
    $this->q = "SELECT stuff FROM table";
    if ($where){
        $this->q .= " WHERE ";
        foreach($where as $x){
           $this->q .= implode(" ", $x);
           if (!notLastElement) $this->q .= " AND ";
        }
    }
}

我似乎建议使用end（），reset（），slice，for循环计数器等等。但似乎没有人同意一个答案。我相信end（）不会在我的循环中起作用。谢谢你的帮助。

它应该像插入参数数组一样容易，例如 -

private function someQuery($where = null){
    $this->q = "SELECT stuff FROM table";
    if ($where){
        $parameters = array();
        foreach($where as $x){
            $condition = implode(' ', $x); // I'd review this - why are you forming your parameter array the way that you are?
            array_push($parameters, $condition);
        }
        $conditions = implode(' AND ', $parameters);
        $this->q .= ' WHERE ' . $conditions; // only concatenate once
    }
}

附加未知数量的WHERE参数
