    Displaying HTML links to files in alphabetical order?

    Hello

    I have a script that searches a folder on my server for pdf files then displays links to them on a web page in an unordered list. My questions is... is it possible to change the order that these files are displayed? Eg. alphabeticaly? I can't work out how these files are being displayed by default... it doesn't appear to be by modified date or alphabeticaly?

    Any help greatly appreciated!

    PHP Code:
    <?php 

        $dom 
    = new DOMDOcument (); 
        
    $ul $dom->appendChild ($dom->createElement ('ul')); 
         
        foreach (
    glob ('*.pdf') as $pdf) { 
            
    $li $ul->appendChild ($dom->createElement ('li')); 
            
    $a $li->appendChild ($dom->createElement ('a')); 
            
    $a->appendChild ($dom->createTextNode (str_replace ('_'' 'pathinfo ($pdfPATHINFO_FILENAME)))); 
            
    $a->setAttribute ('href'$pdf); 
            
    $a->setAttribute ('type''application/pdf'); 
        } 
         
        echo 
    $dom->saveHTML(); 

    ?>

    Hi

    I have a script that allows users to download pdf files from my site.

    To make it simple as possible i just dump a new file in and thats it.

    How i make it work is simple.

    I turn the file name into effectively an array.

    orderdisplayed_Title_FileDescription.pdf

    PHP Code:

                               $x 
    explode("_",$filename);
                               
    $title $x[1];
                               
    $description $x[2]; 
    Order displayed is of course automatic as youve discovered. So just put A or B etc or 1 or 2 etc in the file name at start.

    You could simply assign the result of glob() to a variable, then apply the sorting function of preference (e.g. natcasesort()?) to that array, then run your foreach on the sorted array.

    OK... I'm rubbish at this and am having trouble. I've been trying this:
    PHP Code:
    <?php 

        $dom 
    = new DOMDOcument (); 
        
    $ul $dom->appendChild ($dom->createElement ('ul')); 
        
        
    $articles glob('*.pdf') as $pdf);
        
        
    rsort($articles);
         
        foreach 
    $articles) { 
            
    $li $ul->appendChild ($dom->createElement ('li')); 
            
    $a $li->appendChild ($dom->createElement ('a')); 
            
    $a->appendChild ($dom->createTextNode (str_replace ('_'' 'pathinfo ($pdfPATHINFO_FILENAME)))); 
            
    $a->setAttribute ('href'$pdf); 
            
    $a->setAttribute ('type''application/pdf'); 
        } 
        
        echo 
    $dom->saveHTML(); 

    ?>
    I'm getting this error: Parse error: syntax error, unexpected T_AS in.......

    Any guidance would be so appreciated!
