can you post sample input + output files? That will
make it easier.
stomp();
Here's some bash code, which should be a lot faster, because only shell builtins are used. Can be better if you bring samples(in/out) and explain them.

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