我想使用文件类型显示文件列表

<?php
        //scan "uploads" folder and display them accordingly
       $scan = scandir('uploads');

            foreach($scan as $file)
            {
               if (is_image("uploads/$file"))
                { ?>
                    <p><?php echo "this is an image"; ?></p>
            <?php        
                }
              if (is_pdf("uploads/$file"))
                { ?>
                    <p><?php echo "this is an PDF file"; ?></p>
            <?php        
                }
              if (is_html("uploads/$file"))
                { ?>
                    <p><?php echo "this is an HTML file"; ?></p>
            <?php        
                }

    You can do a simple str_pos() / substr() to detect if the string contains a .pdf file extension or a .html or a .png/.jpg.

    Here's some example code:

    if (substr($filename, -4) == '.jpg') {
           echo "Jpeg!";
    }
    

    Just make the other switches for the different file types and you're golden. Ideally, pass all the files to one function and have all the logic contained there.
