Generalized php scripts

[deesse]

HI All,

May I know, how can I generalize my php script and how would that script be like based on these description:

1--The new script should be a ONE php-program that takes a file name (URL) to download as command line parameter.

2--Depending on the extension of the file to download, the program should choose between downloading and unpacking (.ext1 extension), or just downloading (.ext2 and .ext3).

overall working archi.....
