Question

我想计算db中存储的当前时间和时间之间的时差。 d/M/y H:i:s A是MS Sql存储日期和时间的格式。以下代码返回错误的值。

function time_difference($created_time)
{
    $str = $created_time;              // 03/Mar/17 12:35:00 PM
    $today = date('d/M/y H:i:s A');    // 06/Mar/17 06:35:15 AM
    $time_difference = $today - $str;  // Returns 3
}

无论如何都要将$str和$today转换为秒？

Answer 1

如下所示： -

<?php
function time_difference($created_time)
{
        $str = $created_time;              // 03/Mar/17 12:35:00 PM
        $today = date('d/M/y H:i:s A');    // 06/Mar/17 06:35:15 AM
        return $time_difference = strtotime(str_replace('/','-',$today)) - strtotime(str_replace('/','-',$str));
}

echo  time_difference("03/Mar/17 12:35:00 PM");

输出： - https://eval.in/748622

Answer 2

function time_difference($created_time)
{
       $created = DateTime::createFromFormat('d/M/y H:i:s A', $created_time);
       return strtotime('now') - $created->getTimestamp(); 
}

Answer 3

<?php
function time_difference($created_time, $date ='',$new_date ='',$time_diff ='')
{

    $date = DateTime::createFromFormat('d/M/y H:i:s A', $created_time); 
    $new_date = $date->format('Y-m-d h:i:s');
    $time_diff = strtotime(date('Y-m-d h:i:s')) - strtotime($new_date);
    return $time_diff;
}
echo time_difference('03/Mar/17 12:35:00 PM');
?>
