mysqli - 如何在不修改结果集的情况下获取行？

Question

是否可以在不提取行的情况下从mysqli_result中提取值，即不修改结果集，因为我需要在我的代码中完整地需要它？

Answer 1

您也可以将迭代器指回到开头。即..

$result = $mysqli->query($query);
while($row = $result->fetch_assoc())
{
    //do stuff with the result
}
//back to the start
mysqli_data_seek($result,0);

现在指针返回到开头。 mysqli_data_seek

Answer 2

你可以获得所有并存储在数组中......

$results = [];
$sql = mysqli_query($con,"SELECT * FROM WHATEVER");
while ($row = mysqli_fetch_array($sql)) {
    array_push($results, $row);
}
//Now $results is fully populated
