Question

我一直在线查看示例，我发现它们有点神秘或过度。

我需要做的是这样的事情：

$timestamp = time();

然后查明这一天是星期一还是月份？

我确信这是可能的，我只是不知道该怎么做。

Answer 1

实际上，您不需要时间戳变量，因为：

来自php.net的date函数：

使用返回根据给定格式字符串格式化的字符串给定的整数时间戳或当前时间（如果没有时间戳）给出。换句话说，timestamp是可选的，默认为该值时间（）。

if(date('j', $timestamp) === '1') 
    echo "It is the first day of the month today\n";

if(date('D', $timestamp) === 'Mon') 
    echo "It is Monday today\n";

Answer 2

这应解决它：

$day = date('D');
$date = date('d')
if($day == Mon){
    //Code for monday
}
if($date == 01){
    //code for 1st fo the month
}
else{
    //not the first, no money for you =/
}

Answer 3

这将从星期一从mysql中获取

$monday = 1; //tuesday= 2.. sunday = 7

    AND $monday = (date_format(from_unixtime(your_date_column),'%w'))

OR days ..

$day = 1; ///1st in month

    AND $day = (date_format(from_unixtime(your_date_column),'%d'))

只是知道

$date  = date("d"); //1st?
$dayinweek = date("w"); //monday? //as a number in a week what you need more then just "Monday" I guess..

Answer 4

您可以使用：strtotime

$firstdaymonth = strtotime('first day this month');

Answer 5

因为$ date可以是星期一或星期日。应该检查

public function getWeek($date){
    $date_stamp = strtotime(date('Y-m-d', strtotime($date)));

     //check date is sunday or monday
    $stamp = date('l', $date_stamp);      

    if($stamp == 'Mon'){
        $week_start = $date;
    }else{
        $week_start = date('Y-m-d', strtotime('Last Monday', $date_stamp));
    }


    if($stamp == 'Sunday'){
        $week_end = $date;
    }else{
        $week_end = date('Y-m-d', strtotime('Next Sunday', $date_stamp));
    }        
    return array($week_start, $week_end);
}

Answer 6

由于 PHP> = 5.1 ，因此可以使用date('N')，它返回星期几的ISO-8601数字表示形式，其中1是星期一，7是星期日。

所以你可以做

if(date('N', $timestamp) === '1' || date('j', $timestamp) === '1')) {
    echo "Today it is Monday OR the first of the month";
}

PHP - 如何使用$ timestamp检查今天是星期一还是1月1日？
