警告：日期（）預計參數2長，串給出

Question

錯誤：

Warning: date() expects parameter 2 to be long

這是一個回發PHP腳本的一部分，

$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

你click_time領域可能是DATETIME型，並且date()預計第二個參數是時間戳（long）。

嘗試更換線＃2：

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

，或者確保您的click_time場TIMESTAMP類型。
