Greggory Shaw:
Need for help with PHP for my site !

I have some php code for a Hobbes listing on my site that needs some help:

 http://os2notes.net/#ftplist

1) I would like to filter out the .txt files in column one.
2) Add a html link for the filter out .txt item to column two.
2b) Parse the 'Short description' from the README.TEMPLATE & display it !

3) Filter an item by name or partial name.
4) limit the items to be printed.


It would also help me with a new news format I'm working on, RSS to html format.

Thanks

Well, one was easy:

// parse short description
$myFile = $myFile = 'http://hobbes.nmsu.edu/download/pub/incoming/' . $fileinfo['name'];
$lines = file($myFile); //file in to an array not recommeded for large files, use $lines[4] to print short desc.

// get extension
$ext = pathinfo($fileinfo['name'], PATHINFO_EXTENSION);

// filter txt files
if ($ext !== 'txt') {

// rename extension
$textName = preg_replace('"\.(zip|wpi)$"', '.txt', $fileinfo['name']); // rename zip/wpi to txt

// split short description line in two, to print $pieces[1]
$pieces = explode(":", $lines[4]);

// print file listing here
}

// filter item
  $string = $item['title'];

  if(stristr($string, 'netlabs.org newsletter') === FALSE) {
     // filter in match 
  }

Funny note: always work with proofed data ! While I was working on this Hobbes processed the incoming directory.  I went over the code 3 or 4 times wondering why only the README.TEMPLATE was showing.
