需要此功能在周末返回false

Question

Need help with php.

So I am writing this for a shop. This function returns false whenever they are closed (opening at 9:30 and closing at 22:45).

I need it to ALSO return false when the current day of the week is Saturday or Sunday.

Here is the function:

function can_order_now_timeframe(){

 $morning= new DateTime("09:30", new DateTimeZone('Europe/Budapest'));
 $night = new DateTime("22:45", new DateTimeZone('Europe/Budapest'));


 $morning_u = $morning->format('U');
 $night_u = $night->format('U');

 $datenow = new DateTime("now", new DateTimeZone('Europe/Budapest'));
 $timestampnow = $datenow->format('U');


 if(($morning_u<$timestampnow) && ($timestampnow < $night_u)){
 return true;
 }else{
 return false;
 }

}

Thanks for the help.

Answer 1

Using the date object (credits to Icecub)

function isWeekend($datenow){
    $day = $datenow->format('%w');
    if ($day=="0"||$day=="6"){
        return true;
    }else{
        return false;
    }
}

Using date and strtotime in combination with the timestamp ($timestampnow)

If you have PHP >= 5.1:

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

otherwise:

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

A complete code would look like ths. (You can use a function inside a function)

<?php
function isWeekend($datenow){
    $day = $datenow->format('%w');
    if ($day=="0"||$day=="6"){
        return true;
    }else{
        return false;
    }
}

function can_order_now_timeframe(){

    $morning= new DateTime("09:30", new DateTimeZone('Europe/Budapest'));
    $night = new DateTime("22:45", new DateTimeZone('Europe/Budapest'));


    $morning_u = $morning->format('U');
    $night_u = $night->format('U');

    $datenow = new DateTime("now", new DateTimeZone('Europe/Budapest'));
    $timestampnow = $datenow->format('U');


    if(($morning_u<$timestampnow) && ($timestampnow < $night_u) && !isWeekend($datenow)){
        return true;
    }else{
        return false;
    }

}
?>

or you can have it all inside one function like this if you dont think you might need the weekend detection again:

<?php
function can_order_now_timeframe(){
    $morning= new DateTime("09:30", new DateTimeZone('Europe/Budapest'));
    $night = new DateTime("22:45", new DateTimeZone('Europe/Budapest'));

    $morning_u = $morning->format('U');
    $night_u = $night->format('U');

    $datenow = new DateTime("now", new DateTimeZone('Europe/Budapest'));
    $timestampnow = $datenow->format('U');

    $day = $datenow->format('%w');
    if ($day!="0" and $day!="6"){   
        if(($morning_u<$timestampnow) && ($timestampnow < $night_u)){
            return true;
        }else{
            return false;
        }
    }else{
        return false;
    }
}
?>
