php date functions, trouble finding last day of month

[juanc]

With regards to the numerical value of each day of the week.

ie. Sunday is 0,Monday is 1,Tuesday is 2 and so on.

I need the value for the day of the week that falls on the last day of the month. For example this month being August ……….so 31 Aug falls on a Thursday so that would be 4

What I’ve written doesn’t work properly.

[code]
<?php

$month = date('n');
$year = date('Y');

$timestamp = mktime(0,0,0,$month,1,$year);

$numOfdays = date('t',$timestamp);

$lastDayDate = mktime(0,0,0,$month,$numOfdays,$year);

$lastDayNumber = date('w',$lastDayDate);

echo 'The number is ' . $lastDayNumber;

?>

[/code]


This actually works but if I change to being in respect this coming September
($timestamp = mktime(0,0,0,9,1,$year);

it gives me 3 when it should be 6 as 30 Sep falls on a Saturday.  Similarly with October I get 4 when it should be 2 as 31 Oct falls on a Tuesday.

[code]<?php
list($y,$m,$d) = explode("-", date("Y-m-d")); // get current month and year
echo date("w", mktime(0,0,0,$m+1,0,$y)); // day before first day of next month
?>[/code]

Try this...


[code]
<?PHP
$mo=8;
$year = 2006;
echo date('w',strtotime($mo . "/" . date('t',strtotime($mo . "/" . "28" . "/" . $year)) . "/" . $year));
?>
[/code]

Lite...
