PHP strotime不适用于日期和星期几

这里有一个奇怪的。。。非常确定这是一个strotime问题，但我希望能得到一些帮助，解释为什么这会部分起作用

$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );

代码：

$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );

正确输出变量$startMonth、$startDate。（分别为9月22日）

$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );

变量$startFullDate返回1969年12月31日（显然是一个strotime问题，但不确定为什么？）

$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );

变量$startDay总是以Wed的形式返回（同样，这显然是一个strottime问题，但不确定原因？

您正在覆盖原始变量：

$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );

$startDate = date( 'd', $startDate );
^^^^^^^^^^ here

您应该使用不同的名称。

您将

$startDay

和

$startFullDate

设置为另一个

$startDate

行

$startDate=date（'d'，$startDate））？否？您在
$startDate=date（'d'，$startDate）行上将
$startDay
和
$startFullDate
设置为另一个
$startDate
？不
$dateReturnedFromMySQL = '2014-09-22 18:00:00'
$startDate = strtotime( $dateReturnedFromMySQL );
$startMonth = date( 'M', $startDate );
$startDate = date( 'd', $startDate );
$startDay = date( 'D', $startDate );
$startFullDate = date('M d, Y', $startDate );
