PHP：致命错误在非对象上调用成员函数format（）

Question

我将此代码插入timestamp到mySql数据库（i need to this for customize）中：

$datepub = $_POST['datepub'];
$timepub = $_POST['timepub'];
$timedate = $datepub .''.$timepub;
$datetime = DateTime::createFromFormat('Y/m/d h:i:s', $timedate);
$month = $datetime->format('m'); // Line 61
$year  = $datetime->format('Y');
$date  = $datetime->format('d');
$hour = $datetime->format('h');
$minute  = $datetime->format('i');
$sec  = $datetime->format('s');

但是我看到了这个错误：

Fatal error: Call to a member function format() on a non-object in C:\xampp\htdocs\cms\modules\add.php on line 61   

当我echo $timedate输出时：2014/03/1516：45：30

我该如何解决此错误？

Answer 1

纠正如下：

$timedate = $datepub .' '.$timepub;//add a space
$datetime = DateTime::createFromFormat('Y/m/d H:i:s', $timedate); //need capital H

干杯，

Answer 2

你错过了一个空白区域。这一行：

$timedate = $datepub .''.$timepub;

应该是：

$timedate = $datepub . ' ' . $timepub;
