[PHP知识库]php时间字符转换

PHP时间处理以TimeStamp为主。字符串转换可以通过格式符来控制。

    $date=new DateTime('2022-02-24T22:11+08:00');
    echo $date->format('Y-m-d\TH:i:s') . "\n";

function timestamp_to_datetime(int $timestamp)
{
	date_default_timezone_set('PRC'); 
	return date("Y-m-d H:i:s",time());
}

    $code='421126';
    query_obsTime_recent2($conne,$code);
    $row1=$conne->rst->fetch_row();
    $row2=$conne->rst->fetch_row();
    echo $row1[0],"\n";
    echo $row2[0],"\n";
    date_default_timezone_set('PRC'); 
    $dat1=strtotime($row1[0]);
    $dat2=strtotime($row2[0]);
    echo $dat1,"\n";
    echo $dat2,"\n";
    echo $dat1-$dat2,"\n";


2022-05-07T20:16+08:00
2022-05-06T16:11+08:00
1651925760
1651824660
101100

'2022-02-24T22:11+08:00'可以转换成时间，无需自己写解析函数。
