同时输入php时间减法时得到错误的值

如何解决同时输入php时间减法时得到错误的值

$startTime= '07:00:00';
$EndTime = '07:24:13';
$sst = strtotime($startTime);
$eet=  strtotime($EndTime);
$diff= $eet-$sst;
echo $timeElapsed= gmdate("h:i:s",$diff);

这里的答案必须是24分13秒，但我得到的结果是12:24:13。

解决方法

尝试一下：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">

    <persistence-unit name="NewPersistenceUnit">

        </properties>
    </persistence-unit>
</persistence>

您的代码中有一个错字，H必须是大写。
