Question

查询如下

$query = "SELECT password FROM passwordhistory where userid=? order by id desc limit 3";
$stmt2 = $mysqli->prepare($query);
$stmt2->bind_param('i',$id);
$stmt2->execute();
$res=$stmt2->get_result();

while($row=$res->fetch_object()) {
    foreach($row as $t->password) {
        echo $password[1];
    }
}

在上面的代码中我想要打印三个变量的密码。我无法做到这一点。

Answer 1

将您的代码更改为：

$i = 0;
while($row=$res->fetch_object())
{
    foreach($row as $t->password) 
    {
       echo $newPass.$i =  $password[1];
       $i++;
    }
}

Answer 2

我认为你可以使用str_split函数。

foreach($row as $t->password)
{
    $array = str_split($password[1],3);
}
