[PHP-DEV] Invalid Directory Resource? From: John Fuetsch (jfuetsch <email protected>)
Date: 07/10/00

I'm trying to open a directory and print out all files that have $id in the
filename, but when I use the code below, I get "1 is not a Valid Resource"
on the readdir line. The directory exists, and I think I'm calling it
correctly.

The way the site works is it's one file that has a ?id=whatever in the
address. whatever is then looked up in a database and corresponding data is
pumped out through a template. It seems that sometimes when the page is
reloaded (with or without a different id,) sometimes the directory resource
id doesn't change, and then I get the invalid warning. So, is there a way
to somehow reset the directory resource id? Or maybe have it get a new one
each time? (reliably)

Thanks in advance,

John Fuetsch

# Load Directory Into Array

$dir = "images/thumbs";

$handle=opendir($dir);
while ($file = readdir($handle)) {

  if(strstr($file,$id)) {
    $images[count($images)] = $file;
  }

}
# Clean up and sort
closedir($handle);
sort($images);
