php glob（）和$ _SERVER [“DOCUMENT_ROOT”]无法正常工作

Hello!

I am using php glob() and a for loop to display the images in an folder.

Everything is working good if I use a path without $_SERVER["DOCUMENT_ROOT"], but since I'm adding the doc root before the path the images aren't loading in my locolhost site. After uploading the site to my server it does not work at all and the folder cannot be found even if it is the correct path (neither the images nor the image name, size, etc.).

Here's an image of how it looks on my localhost: http://imageuploaderforckeditor.altervista.org/so/localhost.png

Here's an image of how it looks after it is uploaded: http://imageuploaderforckeditor.altervista.org/so/uploaded.png

And here is the function:

function loadImages() {
    require(__DIR__ . '/pluginconfig.php');
    if(file_exists($useruploadpath)){

        $filesizefinal = 0;
        $count = 0;

        $dir = $useruploadpath;
        $files = glob("$dir*.{jpg,jpeg,png,gif,ico}", GLOB_BRACE);
        usort($files, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));
        for($i=count($files)-1; $i >= 0; $i--):
            $image = $files[$i];
            $image_pathinfo = pathinfo($image);
            $image_extension = $image_pathinfo['extension'];
            $image_filename = $image_pathinfo['filename'];
            $size = getimagesize($image);
            $image_height = $size[0];
            $file_size_byte = filesize($image);
            $file_size_kilobyte = ($file_size_byte/1024);
            $file_size_kilobyte_rounded = round($file_size_kilobyte,1);
            $filesizetemp = $file_size_kilobyte_rounded;
            $filesizefinal = round($filesizefinal + $filesizetemp) . " KB";
            $calcsize = round($filesizefinal + $filesizetemp);
            $count = ++$count;

            if($file_style == "block") { ?>
                <div class="fileDiv" onclick="showImage('<?php echo $image; ?>','<?php echo $image_height; ?>');">
                    <div class="imgDiv"><img class="fileImg lazy" data-original="<?php echo $image; ?>"></div>
                    <p class="fileDescription"><span class="fileMime"><?php echo $image_extension; ?></span> <?php echo $image_filename; ?><?php if($file_extens == "yes"){echo ".$image_extension";} ?></p>
                    <p class="fileTime"><?php echo date ("F d Y H:i", filemtime($image)); ?></p>
                    <p class="fileTime"><?php echo $filesizetemp; ?> KB</p>
                </div>
            <?php } elseif($file_style == "list") { ?>
                <div class="fullWidthFileDiv" onclick="showImage('<?php echo $image; ?>','<?php echo $image_height; ?>');">
                    <div class="fullWidthimgDiv"><img class="fullWidthfileImg lazy" data-original="<?php echo $image; ?>"></div>
                    <p class="fullWidthfileDescription"><?php echo $image_filename; ?><?php if($file_extens == "yes"){echo ".$image_extension";} ?></p>

                    <div class="qEditIconsDiv">
                        <img title="Delete File" src="img/cd-icon-qtrash.png" class="qEditIconsImg" onclick="window.location.href = 'imgdelete.php?img=<?php echo $image; ?>'">
                    </div>

                    <p class="fullWidthfileTime fullWidthfileMime fullWidthlastChild"><?php echo $image_extension; ?></p>
                    <p class="fullWidthfileTime"><?php echo $filesizetemp; ?> KB</p>
                    <p class="fullWidthfileTime fullWidth30percent"><?php echo date ("F d Y H:i", filemtime($image)); ?></p>
                </div>
            <?php }

        endfor;
        if($count == 0){
            $calcsize = 0;
        }
        if($calcsize == 0){
            $filesizefinal = "0 KB";
        }
        if($calcsize >= 1024){
            $filesizefinal = round($filesizefinal/1024,1) . " MB";
        }
        echo "
        <script>
            $( '#finalsize' ).html('$filesizefinal');
            $( '#finalcount' ).html('$count');
        </script>
        ";
    } else {
        echo '<div id="folderError">The folder <b>'.$useruploadfolder.'</b> could not be found. Please choose another folder in the settings or <button class="headerBtn" onclick="window.location.href = \'pluginconfig.php?newfoldername='.$useruploadfolder.'\';">create the folder <b>'.$useruploadfolder.'</b></button>.</div>';
    } 
}

Here are the localhost pathes (not the same pathes as the uploaded):

$useruploadfolder = "ckeditor/plugins/imageuploader/uploads";
$useruploadpath = $_SERVER["DOCUMENT_ROOT"]."/eigenedateien/ckeditor/plugins/imgupload/web/demo/ckeditor/plugins/imageuploader/uploads/";

I hope you understand my question :)

Thanks for everything!
