今天和昨天的php日期用法

Question

I am a beginner for php. I am trying to integrate an XML API to my system. Calling code is

$XML = simplexml_load_file('http://my.mydomain.com/stats/report.xml?api_key=XXXXXXXX&start_date='.date('Y-m-d').'&end_date='.date('Y-m-d'));

What I need to do is;

• start_date = yesterday
• end_date = today

I could not find how to describe.

Answer 1

You can simply use strtotime() call like so:

$today = date('Y-m-d', strtotime('today') );
$yesterday = date('Y-m-d', strtotime('1 day ago') );

Answer 2

$Start_Date=date('d.m.Y',strtotime("-1 days"));
$End_Date = date('d.m.y', strtotime('today') );

Answer 3

PHP strtotime() function helps in this:

You could use

$XML = simplexml_load_file('http://my.mydomain.com/stats/report.xml?api_key=XXXXXXXX&start_date='.date('Y-m-d',strtotime('yesterday')).'&end_date='.date('Y-m-d',strtotime('yesterday'));

Yes its that simple, date('Ym-d',strtotime('yesterday')) gives you yesterday's date !!

ref: http://php.net/manual/en/function.strtotime.php

int strtotime ( string $time [, int $now = time() ] )

$time = A date/time string. Valid formats are explained in Date and Time Formats.

$now = This is an optional parameter for the timestamp which is used as a base for the calculation of relative dates.
