警告：date（）期望参数2为长

这是一个回发的PHP脚本部分，

$conv_time = time();
$click_time_to_date = new DateTime(date('Y-m-d h:i:s', $mysql['click_time']));
$conv_time_to_date = new DateTime(date('Y-m-d h:i:s', $conv_time));
$diff = $click_time_to_date->diff($conv_time_to_date);
$mysql['time_difference'] =  $db->real_escape_string($diff->d.' days, '.$diff->h.' hours, '.$diff->i.' min and '.$diff->s.' sec');
$mysql['conv_time'] = $db->real_escape_string($conv_time);
$mysql['ip'] = $db->real_escape_string($_SERVER['HTTP_X_FORWARDED_FOR']);
$mysql['user_agent'] = $db->real_escape_string($_SERVER['HTTP_USER_AGENT']);

Answer 1

您的click_time字段可能属于DATETIME，date()期望第二个参数为时间戳（long）。

尝试用以下代码替换第2行：

$click_time_to_date = new DateTime($mysql['click_time']);

或确保您的click_time字段属于TIMESTAMP类型。
