I am writing a bash shell script. My script has a few user defined parameters. When the script runs the first thing it does is make sure that these parameters are valid. One of the parameters is called YEAR. A valid input for YEAR can be 1997-2000.
One way I have come up with to ensure that YEAR is valid is by using a case statement:
However, that is a simple case! In reality YEAR is valid for 1997-2008. Instead of listing each valid year in the case statement is there a way that I could just place all the valid years into an array and use that? ie:
I have tried that and it doesn't work. Am I close? Is there a better way? Thanks a lot.

NOTES
Note
In PHP versions before 5.0.0 you must use ocicolumnsize(3) instead. This name still can be used, it was left as alias of
oci_field_size(3) for downwards compatability. This, however, is deprecated and not recommended.
SEE ALSO oci_num_fields(3), oci_field_name(3).
