How to pass url to read png files in php -

if do

$dir = './'; $files = glob( $dir . '*.png'); foreach( $files $file) {     echo $file; } ?> 

and store php file in same folder images correct png files.

if change location of php file how can read png files located in other folder?

if do

$dir = 'www.site.com/content/images'; $files = glob( $dir . '*.png'); foreach( $files $file) {     echo $file; } 

it not display anything, necessary php file code in same folder of images?

you shouldn't add "www.site.com" path. should use absolute path root of server (beginning "/": /content/images) or relative path current location of php script (content/images).
