mysqli和php获取对象

Question

我有以下代码：

$sql_latest = "SELECT * FROM tbl_latest ORDER BY id DESC LIMIT 0,3 ";

 $results_latest = $mysqli->query($sql_latest);

 while($row = $results_latest->fetch_object())
 {
  echo $row->id;
 }

如何将结果输入数组，以便我可以执行类似

的操作

echo $ row [1]; echo $ row [2]; echo $ row [2];

Answer 1

我假设你的意思是在一个数组中获取所有行

$sql_latest = "SELECT * FROM tbl_latest ORDER BY id DESC LIMIT 0,3 ";
$results_latest = $mysqli->query($sql_latest);
$rows = array();
while($row = $results_latest->fetch_object())
{
    $rows[] = $row;
}

echo $rows[0]->id;
echo $rows[1]->id;

或者，如果你想要数组中的字段：

while ($row = $results_latest->fetch_array()) {
    echo $row[0];  //Prints the first column
}

Answer 2

您正在使用$ results_latest-＆gt; fetch_ 对象方法
你怎么认为应该用什么方法来获得数组？

Answer 3

mysql_fetch_assoc或mysql_fetch_array

Answer 4

$sql_latest = "SELECT * FROM tbl_latest ORDER BY id DESC LIMIT 0,3 ";

 $results_latest = $mysqli->query($sql_latest);

 while($row = $results_latest->fetch_array())
 {
  echo $row[0];
 }
