<?php
$start    = new DateTime('2013-05-01');
$end      = new DateTime('2013-08-30');
$interval = DateInterval::createFromDateString('1 day');
$period   = new DatePeriod($start, $interval, $end);

foreach ($period as $dt) {
    if ($dt->format("N") == 2 || $dt->format("N") == 4) {
        echo $dt->format("l Y-m-d") . "<br>\n";
    }
}

一些PHP-Fu

$start_date = '2013-05-01';
$last_date = '2013-08-30';

$dates = range(strtotime($start_date), strtotime($last_date),86400);
$days = array('tuesday' => array(), 'thursday' => array());

array_map(function($v)use(&$days){
        if(date('D', $v) == 'Tue'){
            $days['tuesday'][] = date('Y-m-d', $v);
        }elseif(date('D', $v) == 'Thu'){
            $days['thursday'][] = date('Y-m-d', $v);
        }
    }, $dates); // Requires PHP 5.3+

print_r($days);

输出

<?php echo date('Y-m-d', strtotime('next thursday', strtotime($start_date)));

也适用于星期二的课程

请使用以下功能解决方案,

 function daycount($day, $startdate, $lastdate, $counter=0)
    {
        if($startdate >= $lastdate)
        {
            return $counter;
        }
        else
        {
            return daycount($day, strtotime("next ".$day, $startdate), ++$counter);
        }
    }

$start_date = "2013-05-01";
$last_date = "2013-08-30";

echo "Tuesday Count - ".daycount("tuesday", strtotime($start_date), strtotime($last_date));
echo "<br/>";
echo "Thursday Count - ".daycount("thursday", strtotime($start_date), strtotime($last_date));

试试这个

$startDate = strtotime($start_date);
$endDate = strtotime($last_date);
while ($startDate < $endDate) {
    echo date('Y-m-d', $startDate ). "\n";
    // Give the condition to find last Tuesday
    $startDate = strtotime( 'next Tuesday', $startDate );
}

使用DateTime

$start_date = "2013-05-01";
$last_date = "2013-08-30";

$start = new DateTime($start_date);
$clone = clone $start;

$start->modify('next thursday');
$thursday=$start->format('Y-m-d');

$clone->modify('next tuesday');
$tuesday=$clone->format('Y-m-d');

echo $thursday; //2013-05-02
echo $tuesday; //2013-05-07

我们需要对象,因为如果在tuesday之前的时间段thursday之前我们将有下一个tuesday。但是你可以修改一些代码来使用一个对象。

借助几个php日期函数,可以轻松解决这个问题。

<?php

// Create the from and to date
$start_date = strtotime("2013-05-01");
$last_date  = strtotime("2013-08-30");

// Get the time interval to get the tue and Thurs days
$no_of_days = ($last_date - $start_date) / 86400; //the diff will be in timestamp hence dividing by timestamp for one day = 86400
$get_tue_thu_days = array();

// Loop upto the $no_of_days
for($i = 0; $i < $no_of_days; $i++) {
    $temp = date("D", $start_date);
    if($temp == "Tue" || $temp == "Thu") {
      $get_tue_thu_days[] = date("D/M/Y", $start_date); //formating date in Thu/May/2013 formate.
    }
    $start_date += 86400;
}

print_r($get_tue_thu_days);
