I have been writing some code that visits each directory stored within one
directory in turn, pics a random image from it and displays that image.
I have the code working fine, apart from one small quirk that I can't really
understand.
In one version of the implementation, the directories appear to be getting
accessed in the order they are uploaded to / edited on the server starting
with the most recent upload/change - which is handy because it is what I
wanted.
But in another slightly different version of the same bit of code, it lists
them in some weird order that I can't fathom.
I suppose my question put simply is, what is the default ordering of
directories when PHP uses the readdir method? And is there anyway to force a
specific ordering to the directories before PHP searches down them?
Any help would be greatly appreciated.
Regards,
Toby

According to php.net, the readdir() function simply reads the contents of
the directory in the order which they are stored by the filesystem.
One way to force the order would be to loop through the contents of the
directory and store the directory names into an array, and use the functions
filemtime() and sort() to sort the array.
Hope that helps,
Brad

Whatever order the OS decides to use.
In practice, it's whatever is convenient for that particular file system.
So FAT, NFTS, Reiser, ext2, ext3, and so on could all behave differently.
For that matter, the OS could decide to randomize them, just for fun,
if it wanted to.

Not with just opendir/readdir.
You could use exec() with "ls" to get them in various orders.
You could walk through and make an array and then sort.

If you're on PHP 5, look at scandir(). It gives you an array of all of the
files/directories in a given directory, which you can then sort with sort()
or usort() or whatever. If you're on PHP 4, there's a backport of it in
PEAR::PHP_Compat that doesn't actually require the rest of PEAR to
function. :-)

Hello all,
Again a question on the new DOM functions...
The loadHTML function doesn't support any attribute and I'm wondering how to
handle non-text content. Image tags from source webpage are loaded as "objects"
or whatever; they appear as special chars("show source" from browser shows big
empty spaces)... Isn't it possible to "load" the real source code? Special
characters, like the german "ä" is also badly converted into some bizarr "ä"
equivalent...
I tried both functions loadHTML($string) ($string = file_gets_content(url)) and
loadHTMLFile(url). Both with the same result...
Has anyone an idea how to do it?
Thanks

How are you getting that output?
Remember most of the functionality - other than the saveXML(),
saveHTML() functions - output using UTF-8 (which you would need to
convert to what ever encoding you need).

Well I did try before loadHTML call:
$doc = new DomDocument('1.0', 'iso-8859-1');
Maybe it's a problem that the source webpage I'm loading has no charset
declaration. It solely uses:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html lang="de" xmlns="http://www.w3.org/1999/xhtml";>
Don't know if that has an influence...
> How are you getting that output?
About the output I make, I don't use the saveHTML function because I just cut
some parts of the source (grabbed with getElementById() and other related
functions) and only need them, so I just "echo" them into a new document.

Is there a meta tag that specifies the encoding? When loading HTML that
is also used to determine the encoding. I think I need to clarify the
encoding issue:
I'll bet when the document is loading, the encoding is being properly
detected. When working with the elements however you are getting hung up
on the UTF-8 factor....
you probably do something like the following:
$myelement = getElementById('someid');
print $myelement->textContent;
That right there will output the textual content in UTF-8 (the garbled
characters). It does not take into consideration the encoding used in
the origional document. This is just how the xml functions work. Now...
You really need to do something like:
$text = $myelement->textContent;
print iconv("UTF-8", <output encoding>, $text);
If the encoding is in the meta tag, typically encountered as:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
If you add the content to a dom node, you do not change the encoding
since the functions all work on UTF-8. The document to which the content
is being added however, must be set to use the desired encoding. I am
assuming you are doing what I previously explained though.

This does nothing. loadHTML() causes a new underlying document and
replaces the one you created with the new DOMDocument() call. That is
only pertinant when you are manually building a document.

2006/9/14, Norbert Wenzel <[EMAIL PROTECTED]>:
Hi,
just for fun I tried the following code:
<code>
for($letter = 'A'; $letter <= 'Z'; ++$letter) {
echo($letter . ' ');
}
</code>
What surprised me was the output, which looked like this:
A B C [...] Y Z AA AB AC [...] YY YZ
I don't have any idea how these letters get printed out, so I'd
appreciate any guesses or explanations.
thanks,
Norbert

If I'm reading this correctly, you've created a table of every single
date, just to provide a JOIN table of massive proportions?
That's... Not Good (tm) almost for sure...

Now it sounds like you are inserting even MORE entries into another
table to make an even more confusing JOIN...

"SELECT id FROM dates WHERE date = '$month/$day/$year'"
has always worked for me...
If date is a timestamp or datetime, you have to convert THAT to a
date, so that the hours:minutes:seconds don't mess you up.
You're making all of this way too hard ... :-)
Re-think the concept of having a row for every possible day.
Just make sure all your tests for date equality are using the same
type of data -- DATE, not DATETIME, TIMESTAMP, etc.

PHP's use transsid setting in php.ini does exactly that, only with the
session ID, and you don't have to do nothing except turn it on. :-)

Using PHP SESSION with the transsid "on" means you can have the
session last reliably for up to 2 years, if you want to.
That's what I would do, personally, and then you can simplify your
code quite a bit...

See if "/Volumes" exists.
Then if "/Volumes/foresight" exists.
Then iterate through each with opendir/readdir and see what's in there.
Eventually, you will probably stumble over the issue...

Hehe, you gave me some pretty good ideas to make my code sit
safely elsewhere and leave them wondering where the entire site is
coming from. Even if i dont get anything done remotely, at least i
learned some nice things from you guys, so thanks anyway.
And i love my job...although i get paid miserably.:-P (oh,
and the college i work at is practically an all-girls college...so at

Again, big thanks.

Hi all. I have a session issue and wondered if anyone else has encountered
this:
I have an app where a user fills out 3 forms. In each case, after validation
and cleaning the form data is passed into session variables and after the
final submission the data is entered into the database. I am using both
Firefox and IE6 on Windows XP and the system works like a dream. However, a
user testing on IE6/XP is having some problems. The values from the first
form are not being passed into the session.
When each form is successfully processed the user is redirected to the next
stage using header('Location...'). I call session_write_close before that to
ensure the session data is written out before the redirect, but the problem
persists.
Anyone recognise this issue. It is not IE-specific as it happens to me on
Firefox intermittently. I am at my wits end! Thanks in advance for any help!
