Why Does My PHP Weekend Date Check Always Return False?

Verifying Weekend Dates in PHP

While attempting to determine if a given date falls within a weekend, you've noticed that your existing function consistently returns 'false.' Let's delve into your code and understand the reason behind this seemingly erroneous behavior.

The challenge lies in the way you're parsing the date. Your code uses the date() function to extract the day of the week as a string (e.g., "Saturday" or "Sunday"), and then compares it to those exact strings. This approach can be problematic due to case sensitivity and the possibility of typos.

Improved Approach:

Instead, you can leverage PHP's built-in date functions to simplify this task. Here are a couple of recommended solutions:

For PHP 5.1 and later:

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

This function uses the date('N') function to retrieve the day of the week as an integer (1-7), where 6 and 7 represent Saturday and Sunday, respectively. By comparing the result to 6, you can accurately determine if the date falls on a weekend.

For earlier versions of PHP:

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

For PHP versions prior to 5.1, you can still obtain the day of the week as an integer using date('w'). In this case, you'll need to check for both Sunday (0) and Saturday (6) as weekend days.
