How Can I Write a PHP Function to Check if a Date is a Weekend?

PHP Function to Determine if a Date Falls on the Weekend

A common programming task involves checking if a given date is a weekend day, Saturday or Sunday. However, occasionally, problems arise when implementing this functionality.

Consider the following PHP function:

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";
    }
}

When called with $isthisaweekend = isweekend('2011-01-01');, this function consistently returns "false." To resolve this issue and determine if a date is indeed a weekend, consider employing one of the following methods:

For PHP versions 5.1 and above:

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

For earlier PHP versions:

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

These improved functions accurately identify weekends by examining the day of the week (date('N')) or weekday (date('w')) properties of the date object.
