通过SAP周、日期、时间和时间戳格式扩展PHP的DateTime类。通过SAP时间格式扩展PHP的DateInterval类。

• SAP周格式为 <year><week>
• SAP日期格式为 <year><month><day>
• SAP时间格式为 <hour><minute><second>
• SAP时间戳格式为 <year><month><day><hour><minute><second>

用法

composer require php-sap/datetime:~1.0.0

将SAP周字符串解析为DateTime对象。

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = SapDateTime::createFromFormat(SapDateTime::SAP_WEEK, '201846');
echo $dateTime->format('o \w\e\ek W') . PHP_EOL;
/**
 * Output: 2018 week 46
 */

将DateTime对象格式化为SAP周字符串

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = new SapDateTime('2018-10-19 08:09:10');
echo $dateTime->format(SapDateTime::SAP_WEEK) . PHP_EOL;
/**
 * Output: 201842
 */

将SAP日期字符串解析为DateTime对象

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = SapDateTime::createFromFormat(SapDateTime::SAP_DATE, '20181101');
echo $dateTime->format('Y-m-d') . PHP_EOL;
/**
 * Output: 2018-11-01
 */

将DateTime对象格式化为SAP日期

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = new SapDateTime('2018-12-31 09:10:11');
echo $dateTime->format(SapDateTime::SAP_DATE) . PHP_EOL;
/**
 * Output: 20181231
 */

将SAP时间字符串解析为DateTime对象

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = SapDateTime::createFromFormat(SapDateTime::SAP_TIME, '132001');
echo $dateTime->format('H:i:s') . PHP_EOL;
/**
 * Output: 13-20-01
 */

将SAP时间字符串解析为DateInterval对象

此示例使用25小时来展示如何结合使用DateInterval对象和DateTime对象。请注意，format()方法更类似于PHP的sprintf()，而不是date()。

<?php
use phpsap\DateTime\SapDateInterval;
$time = SapDateInterval::createFromDateString('252003');
echo $time->format('%H:%I:%S') . PHP_EOL;
/**
 * Output: 25:20:03
 */
$date = new DateTime('2018-11-01 00:00:00');
$date->add($time);
echo $date->format('Y-m-d H:i:s');
/**
 * Output: 2018-11-02 01:20:03
 */

将DateTime对象格式化为SAP时间

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = new SapDateTime('21:45:05');
echo $dateTime->format(SapDateTime::SAP_TIME) . PHP_EOL;
/**
 * Output: 214505
 */

将DateInterval对象格式化为SAP时间

<?php
use phpsap\DateTime\SapDateInterval;
$time = new SapDateInterval('PTH21M45S05');
echo $time->format(SapDateInterval::SAP_TIME) . PHP_EOL;
/**
 * Output: 214505
 */

将SAP时间戳解析为DateTime对象

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = SapDateTime::createFromFormat(SapDateTime::SAP_TIMESTAMP, '20181019080910');
echo $dateTime->format('Y-m-d H:i:s') . PHP_EOL;
/**
 * Output: 2018-10-19 08:09:10
 */

将DateTime对象格式化为SAP时间戳

<?php
use phpsap\DateTime\SapDateTime;
$dateTime = new SapDateTime('2018-12-31 09:10:11');
echo $dateTime->format(SapDateTime::SAP_TIMESTAMP) . PHP_EOL;
/**
 * Output: 20181231091011
 */
