Why does the date "W" not work? But all others work?

artist19

I'm having a trouble with the code only with one letter "W" based on the script far below.

The line $day = date('W'); does not work at all but all other lines work. E.g.

$day = date('j');
$day = date('w');
etc

They work. But 'W' does not work. Why?

I tried the array to add:
0 => "anydir/apage.php",

Not working.

01 => "anydir/apage.php",

Also not working. What is wrong? Thanks much in advance.

<?php
$content = array(
1 => "dir1/page1.php",
2 => "dir2/page2.php",
3 => "dir3/page3.php",
[..... ]

365 => "dir/page365.php"

);
$day = date('W');
$file = isset($content[$day]) ? $content[$day] : 'dir/fail.php';
include $file;

What do you mean "does not work"? What does it return and what do you expect it to return?
It's supposed to return a string representing the current week of the year (currently it's still week 1, which started on the 7th of January, so it should be returning "01").

1) I expect the file (1 => "dir1/page1.php") to be returned. Instead, I get the file dir/fail.php appeared on the page. Even the pathname/file is correct. I tested the file/pathname on day 7 (today) under $day = date('z') and the page1.php shows but does not show under the line $day = date('W').

2) I tested. <?php
$day = date("W");
echo $day; ?>
And, it shows 01.

It has been working fine all these last months (maybe since July or so) but it does not work this first week of the year. No idea why.

<?php
$content = array(
1 => "dir1/page1.php",
2 => "dir2/page2.php",
3 => "dir3/page3.php",
[..... ]

53 => "dir/page53.php"

);
$day = date('W');
$file = isset($content[$day]) ? $content[$day] : 'dir/fail.php';
include $file;

Comes from the fact
that W returns a string '01'

but we can make the string into one INTEGER value 1
using [man]intval[/man]

try this:

$day = intval(date("W"));

Thank you very much. It works! I am grateful to you.

Btw, out of curiosity, how does one make one week earlier? Something like strtotime("- 1 week") ? How does it work with the following line?

$day = intval(date("W"));

If you mean how to get last week.

// first way
// simply subtract -1
$day = intval(date("W")) -1;

echo $day;

// Another way
$day = intval(date("W"));
$day--;  // means decrease $day with 1

echo '<hr>';
echo $day;

Won't work. Think about it. What happens during week 1?

code=phpdate('W',strtotime('last week'))[/code]
