检查日期是否是周末 PHP [英] Checking if date is weekend PHP

问题描述

这个函数似乎只返回false.你们中有人得到同样的吗?我确定我忽略了一些东西，但是，新鲜的眼睛等等......

This function seems to only return false. Are any of you getting the same? I'm sure I'm overlooking something, however, fresh eyes and all that ...

function isweekend($date){
    $date = strtotime($date);
    $date = date("l", $date);
    $date = strtolower($date);
    echo $date;
    if($date == "saturday" || $date == "sunday") {
        return "true";
    } else {
        return "false";
    }
}

我使用以下方法调用该函数:

I call the function using the following:

$isthisaweekend = isweekend('2011-01-01');

推荐答案

如果你有 PHP >= 5.1:

If you have PHP >= 5.1:

function isWeekend($date) {
    return (date('N', strtotime($date)) >= 6);
}

否则:

function isWeekend($date) {
    $weekDay = date('w', strtotime($date));
    return ($weekDay == 0 || $weekDay == 6);
}
