blocks|key|506122|text|首先，PHP中的日期/时间函数非常慢。所以我尽量给他们打电话。您可以使用getdate()函数来完成这一任务。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|506123|这里有一个灵活的解决方案：|506124|/**

{

First of all, date/time functions in PHP are really slow. So I try to call them a little as possible. You can accomplish this using the <a href="http://php.net/manual/en/function.getdate.php" rel="nofollow"><code>getdate()</code></a> function.

Here's a flexible solution:

<pre><code>/**
 * Gets the timestamp of the beginning of the week.
 *
 * @param integer $time A UNIX timestamp within the week in question;
 * defaults to now.
 * @param integer $firstDayOfWeek The day that you consider to be the first day
 * of the week, 0 (for Sunday) through 6 (for
 * Saturday); default: 0.
 *
 * @return integer A UNIX timestamp representing the beginning of the week.
 */
function beginningOfWeek($time=null, $firstDayOfWeek=0)
{
 if ($time === null) {
 $date = getdate();
 } else {
 $date = getdate($time);
 }

 return $date[0]
 - ($date['wday'] * 86400)
 + ($firstDayOfWeek * 86400)
 - ($date['hours'] * 3600)
 - ($date['minutes'] * 60)
 - $date['seconds'];

}//end beginningOfWeek()
</code></pre>

blocks|key|484621|text|我使用以下代码片段：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484622|public+static+function+getTimesWeek($timestamp)+{

++$infos+=+getdate($timestamp);
++$infos["wday"]+-=+1;
++if($infos["wday"]+==+-1)+{
++++$infos["wday"]+=+6;
++}

++return+mktime(0,+0,+0,+$infos["mon"],+$infos["mday"]+-+$infos["wday"],+$infos["year"]);
}|code-block|syntax|javascript|484623|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I use the following snippet of code:

<pre><code>public static function getTimesWeek($timestamp) {

 $infos = getdate($timestamp);
 $infos["wday"] -= 1;
 if($infos["wday"] == -1) {
 $infos["wday"] = 6;
 }

 return mktime(0, 0, 0, $infos["mon"], $infos["mday"] - $infos["wday"], $infos["year"]);
}
</code></pre>

blocks|key|506127|text|用这个来获得你想要的工作日的时间戳，而不是“星期六”写一周的第一天：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|506128|strtotime('Last+Saturday',mktime(0,0,0,+date('m'),+date('d')%2B1,+date('y')))|code-block|syntax|javascript|506129|例如:在上面的代码中，您可以得到上周六的时间戳，而不是本周的星期六。|506130|请注意，如果平日现在是星期六，这将返回今天的时间戳。|506131|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Use this to get timestamp of which weekday you want, instead 'Saturday' write first day of the week:

<pre><code>strtotime('Last Saturday',mktime(0,0,0, date('m'), date('d')+1, date('y')))
</code></pre>

for example: in above code you get timestamp of last saturday, instead of this week's saturday.

note that, if the weekday is Saturday now, this will return today time stamp.

Need to find the timestamp for the first minute of the first day of the current week.

What is the best way to do this?

<pre><code>&lt;?php

$ts = mktime(); // this is current timestamp

?&gt;
</code></pre>

PHP timestamp - first day of the week
