does readdir not read it in numerical order ?

[pooker]

here is some of my basic code

 

while($folder = readdir($dir)  ){

if ($folder != '.' && $folder != '..') {

$number = $number +1;

?>

<option value="<? echo $folder ?>">chapter <? echo $number ?></option>

<?

}

}

 

in the next page it uses echo folder to reference the image like this

 

img src = /mangareadr/$series/$folder/$number.png 

 

dont worry about the way the code looks because I was just wrighting a short example, and the code works with passing and everything my problem is the way it readdir reads the folder. 

 

In the folder here is how it is setup

 

chapter1

chapter2

chapter3

etc,....

 

So you would assum it would read it like that right?  Well it doesn't, readdir reads mine backwords for some reason so if a user clicks on chapter 4 it would give them chapter 1, chapter 3 would give them chapter 2 and so on in reverse order.  Because I used the number incrementer to increase in number I thought this would work but it does not.  Hop that is clear and thanks for the help ^^

You could use sort()

 

Loop through, and add each file to an array, and then use sort()

readdir() returns files in the order they are in in the file system.

 

To get a sorted list, either read the file names in to an array and sort them or use the glob() function, which sorts the results for you.
