Question

我已经阅读了本主题Constructing UPDATE statements using associative arrays in PHP，但是与我所需要的有所不同。

我有一张桌子t1。

+--------------+----------------+----------------+------------+
| money        | exp            | uid            | remark     |
+--------------+----------------+----------------+------------+
| 9999         | 9999           | 1              |            |
| 1234         | 567            | 2              |            |
| 8887         | 88             | 3              |            |
+--------------+----------------+----------------+------------+

我想创建一个名为function的PHP jnupdateuser来更新此表，例如：

jnupdateuser(array('money'=>10000,'exp'=>10000),1);

之后的数据将是这样：

+--------------+----------------+----------------+------------+
| money        | exp            | uid            | remark     |
+--------------+----------------+----------------+------------+
| 10000        | 10000          | 1              |            |
| 1234         | 567            | 2              |            |
| 8887         | 88             | 3              |            |
+--------------+----------------+----------------+------------+

如果这样做：

jnupdateuser(array('remark'=>'None'),2);

比数据将是这样：

+--------------+----------------+----------------+------------+
| money        | exp            | uid            | remark     |
+--------------+----------------+----------------+------------+
| 9999         | 9999           | 1              |            |
| 1234         | 567            | 2              | None       |
| 8887         | 88             | 3              |            |
+--------------+----------------+----------------+------------+

我的代码如下：

function jnupdateuser($jnparams = array(),$uids){

    $conditionStrings = array();
    foreach ($jnparams as $column => $value) {
        //how to create this part to update my table? or maybe I was totally wrong?
    }

    return DB::query("UPDATE ".DB::table('game_jnmx_user')." SET ??? = ??? WHERE uid = $uids "); 
}

DB::query是我的模板语言，与mysqli_query相同，DB::table也是模板语言；

谢谢。

尝试类似的事情：

function jnupdateuser ($jnparams = [], $uid)
{
    if (empty($jnparams)) {
        return true;
    }

    $conditions = [];
    $uid = (int) $uid;

    foreach ($jnparams as $column => $value) {
        $conditions[] = "`{$column}` = '{$value}'";
    }

    $conditions = implode(',', $conditions);

    return DB::query("UPDATE ".DB::table('game_jnmx_user')." SET {$conditions} WHERE uid = {$uid}");
}

它根据输入参数构建SET，我添加了一些验证。请注意，这里应该以某种方式转义或清理放入数据库的数据，因为它容易受到SQL注入的攻击。</ p>
