PHP Help Needed
 

So I am trying to spruce up my image mod mirror page... I am running into problems with trying to sort the files to be in alphabetical order (and hopefully be able to include options to sort in other methods as well). No, I am not going to write this to use a database. It does not sort properly, and I have no idea how to make it do so. Yes, there is a lot of theoretical code commented out. http://forum.shrapnelgames.com/images/icons/icon12.gif The sorting portion begins at this like:

// Sorting that doesn't work. :'S

Here is the code:

http://imagemod.spaceempires.net/indexmda.txt

And here is the script running:

http://imagemod.spaceempires.net/indexmda.php

Re: PHP Help Needed
 

Will check now.

Edit1:

This is an included file, right.
As I get errors for missing definition of index, numitems, full etc....

Will check further..

Edit2:

Copying the script to my server and the files in the directory (to be sorted) and removing inclusions of header and footer, gives too many errors to even start debugging.
If I'll dig into I ought to have more...
I'll skip all else and just look at the sorting.

Re: PHP Help Needed
 

I don't get any errors about missing definitions... that, and I don't think it is necessary to explicitly define variables separately to just using them in PHP.

The file is not included in anything.

Re: PHP Help Needed
 

Note how there are no errors when it is running under a Linux environment (on the se.net server)...

Re: PHP Help Needed
 

Ok, then I can't explain all the errors.
Anyway, this sorts the names right It seems;

http://pbw.ath.cx/sort.txt

test

http://pbw.ath.cx/sort.php


And that's kind of strange as I haven't altered anything significant.
Can it be the multiarray that messes things up??

Edit: Ahh, I run win server...

Re: PHP Help Needed
 

Sorting a normal array is not a problem. I could just call the asort() function if that were the case. The problem is in sorting a 2D array.

Re: PHP Help Needed
 

What I've done is to define filenames[array] at the same time as Filearray in the beginning.
And started the counter at 1 instead of zero.

As this work I can't be of any help in rooting out your problem, sorry.

Re: PHP Help Needed
 

<font size="2" face="sans-serif, arial, verdana">That does not work, because each filename has 4 other variables that go along with it that must be kept lined up. http://forum.shrapnelgames.com/images/icons/icon9.gif

Re: PHP Help Needed
 

<font size="2" face="sans-serif, arial, verdana">Yeah, that's what I meant with Multiarray, instead of simple array, my own vocabulary I guess....

How about making a simple 1D array also with only filenamess, and then sort that and let the multiarray (2D) follow in the sorting at the same time;

Define multiarray[1..10][1..10]
filenames_only[1..10]

Sort:
If filename[1]>Filename[2]
{
max=[1]
}

loop it and sort it
{
first filename is filename[max]
first multiarray is multiarray[max]
}


?

Re: PHP Help Needed
 

http://se2.php.net/array_multisort

can this be the answer?

Re: PHP Help Needed
 

Well.. that sorted them in a new order... not alphabetical though. http://forum.shrapnelgames.com/images/icons/icon9.gif

http://imagemod.spaceempires.net/indexmda.php

Maybe my selection sort is a bit off...

Looking at link now.

Re: PHP Help Needed
 

Strange indeed!

Edit: I can't really see any logic in the sorting http://forum.shrapnelgames.com/images/icons/icon10.gif

Re: PHP Help Needed
 

Now look at it when it is using multisort... almost in order, but not quite. http://forum.shrapnelgames.com/image...s/confused.gif

Re: PHP Help Needed
 

I think this takes sleeping on.....

Re: PHP Help Needed
 

I fail to see a problem with this line:

array_multisort($fileArray, SORT_ASC, SORT_STRING);

Re: PHP Help Needed
 

Can there somwhow be a character zero involved in the sorting, as I guess the string of the filename starts with character one.
So if it tried to sort with a non existant character it would get a random one??

What if you try to define that it should sort by characters 1-3 in the filenmane?

Very Wild guess!!

Re: PHP Help Needed
 

How about case?
Transform all to lowercase first before sorting?

Edit:

array_multisort(StrToLower($fileArray));


Or rather make it to lowercase when reading in the files, as the above propably won't work.

Re: PHP Help Needed
 

They are all lowercase to begin with.

Re: PHP Help Needed
 

Here is the result from running the original file you posted on my server:

http://pbw.ath.cx/sort2.php

As you can see, it sorts them right but it doesn't display the Last file.
(Ignore all the errors and skip to the bottom)

(I've downloaded all the zip files.)

So it seems to perhaps be something with linux filesystem??

Re: PHP Help Needed
 

Could be. I think all of those errors are due to misconfigurations in your PHP files... I only used standard PHP functions and such, and did not define anything with any names given by the errors.

Re: PHP Help Needed
 

<font size="2" face="sans-serif, arial, verdana">I think it's the parameters in stristr that needs to be surrounded by quotes for the errors to disappear.
I have standrad settings for most PHP settings except file sizes and magic quotes.

Re: PHP Help Needed
 

<font size="2" face="sans-serif, arial, verdana">You have a wrong parameter. Array_multisort requires an array, not a multi-dimensional array. You have to modify $fileArray a bit. Now it's $fileArray[$counter][0], change it to $fileArray[0][$counter]. Then you can sort it easily. For example:

array_multisort($fileArray[0], SORT_ASC, SORT_STRING);//sorts by names.

Have you noticed when you use $file = readdir($dir_handle) you get first "." and then ".." and but then real filenames.

Re: PHP Help Needed
 

Fyron, did you get the sorting working or did you lost interest to the whole thing?
