Parsing a directory for specific files

Hi, does anybody know how to solve the following task? I'd like to generate a dynamic page, which contents come from txt-files. The files will be in a directory called content (from the page: ../content) and they are labeled with date and (within one day) increasing numbers, e.g. 20030108-1.txt, 20030108-2.txt, 20030108-3.txt, 20030109-1.txt, 20030110-1.txt, 20030110-2.txt The script should parse the file names and get the most recent five ones! The text inside should be included in the page -> but this is not the problem, the task mentioned above is the problem! Thx in advance for these who can deliever solutions or ideas! Dirk
