获取MySQL中的总行数

Question

$rowCount = $conn->query('SELECT COUNT(*) FROM Users');
echo '<pre>'.print_r($rowCount,1).'</pre>';

收益:

mysqli_result Object
(
    [current_field] => 0
    [field_count] => 1
    [lengths] => 
    [num_rows] => 1
    [type] => 0
)

...虽然我在PHPMyAdmin中看到的表有978行.

您正在使用print_r生成查询中的行数.您的查询只返回一行,即行数.

试试这个:

$rowCount = $conn->query('SELECT COUNT(*) as rowNumber FROM Users');
$row = $rowCount->fetch_assoc();
echo $row['rowNumber'];
