Re: Reading directory contents

[Jim Plush <jiminoc@xxxxxxxxx>]

what you need is to make a recursive function, that is a function that 
calls itself

like

function open_dir()
{
   if(is_dir($my_dir))
    {
       open_dir();
    } else {
      // read files here
     }

}

basically you're saying... I'm reading the top level directory, are you 
a file? ok I'll read you, are you a directory? ok I'll open you up and 
read your files, and it continues until all files are read. You can 
stored the data into an associative array and you can use that array 
later to generate your data. hope that helps, if not google recursive 
functions
