glob returning empty array


Recommended Posts

Hi all

 

I am trying to display a list of images contained withina folder.

 

I am using the following code

 

 

<?php
    //Path to folder which contains images
    $dirname = $shopConfig['url'].'images/flags/';
    //echo $dirname;
     
    //Use glob function to get the files
    //Note that we have used " * " inside this function. If you want to get only JPEG or PNG use
    //below line and commnent $images variable currently in use
    print_r(glob($dirname."*"));
    $images = glob($dirname."*.png");
    //Display image using foreach loop
    foreach($images as $image){
        
    //print the image to browser with anchor tag (Use if you want really  )
    echo '<a href="'.$image.'" target="_blank"><img src="'.$image.'" height="100" width="100" /></a>';
    }    
   ?>

 

I know there are images within the folder, however when I print the array it is empty.

 

Can anyone point out what is wrong with the code and where I have gone wrong?

 

Thanks
