rtrim problem

[crwtrue]

i have a directory read program and i dont want to display txt files in listing. I am using rtrim function, like this:

rtrim($files[$i], "text1.txt")

this only works in one textfile and i would like to get rid of them all!

if your definition of a text file is that it has an txt extension, i.e. <anyfilename>.txt is the text files you want to avoid in the listing:

foreach($files as $filename)
{
   if(!strcasecmp(substr($filename, -4), '.txt'))
   {
      // Perform your display here like
      echo $filename;
   }
}
