How could I know if a day is sunday on a calendar?

[giba]

Hi There, I am working on a calendar, and I am with a problem.

How could I know if the day is a sunday?

Because I need to perform a sum of extra tax based on the weekday,

and if it is Sunday it's applied extra tax.

 

But for solving this post, print it as bold face is OK for me,

because I have the Math already done, just need to get the sunday.

Thanks in advance!

 

 

Take a look at my working calendar

 

<?php

 

$monthNames = Array( "January",  "February",  "March",  "April",  "May",  "June",  "July",  "August",  "September",  "October",  "November",  "December");

 

if ( !isset( $_REQUEST["month"] ) ) {  $_REQUEST["month"] = date("n" ); }

 

if ( !isset( $_REQUEST["year"] ) ) {  $_REQUEST["year"]  = date("Y" ); }

 

$cMonth = $_REQUEST["month"];

$cYear  = $_REQUEST["year"];

 

$prev_year = $cYear;

$next_year = $cYear;

 

$prev_month = $cMonth-1;

$next_month = $cMonth+1;

 

if ( $prev_month == 0 ) {

    $prev_month = 12;

    $prev_year = $cYear - 1;

}

 

if ( $next_month == 13 ) {

    $next_month = 1;

    $next_year = $cYear + 1;

}

?>

I've only glanced at your script, but couldn't you just go

 

date("l", $timestamp);  //Lowercase L

 

or

 

date("D", $timestamp);  ?

 

 

[giba]

Yes, I know it,

but I would like to know how to make the calendar

do some action if the day is a Sunday, like to make it in bold.

How do I implement it, because I have a number for the days

and what is exactly the relation between the days and the

date('l',$timestamp).

What can I get a visual sign of the Sundays?

 

[premiso]

getdate Would that work out for you?

[giba]

Well, I've found that the line:

 

( $i % 7 )

 

does the trick for Sundays.

 

So now, I can style the Sunday based on this operation.

[fook3d]

date() will give you more information about date().

 

date('l', $timestamp); will return Sunday if the date you are viewing it is a sunday.

 

So surely a simple if statement will make it bold?

 

<?php
$day = date('l', $timestamp);
if($day == 'Sunday')
    echo '<b>' . $day . '</b>';
else
    echo $day;
?>

 

Or am I missing something?

[samshel]

or you can try...

 

<?php
                    $timestamp = mktime( 0, 0, 0, $cMonth, 1, $cYear );
                    $maxday    = date( "t", $timestamp );
                    $thismonth = getdate( $timestamp );
                    $startday  = $thismonth['wday'];

                    for( $i=0; $i < ( $maxday+$startday ); $i++ ) {

                        if( ( $i % 7 ) == 0 ) { echo "<tr>\n"; }
                        if( $i < $startday ) { echo "<td></td>\n";}
                       else {
                            if(date("N", strtotime($cYear."-".$thismonth."-".($i - $startday + 1))) == 7) {
                                echo ($cYear."-".$thismonth."-".($i - $startday + 1)). " is Sunday !! Hurray !!";
                            } else {
                                echo ($cYear."-".$thismonth."-".($i - $startday + 1)). " is a WeekDay  and my boss just called !!";
                            }
                            echo "<td align='center' valign='middle' height='20px;'>". ( $i - $startday + 1 ) . "</td>\n";

                        }

                        if( ( $i % 7 ) == 6 ) { echo "</tr>\n"; }
                    }
?>
