Hi,
I have an ascii file containing information. This file is n x m lines.
Is there a way to generate an ascii file where the information is stored as n x m table instead? The m columns should be tab separated.
Thanks a lot,

retrieved. The $field_offset starts at 0.
Returns an object containing field information. The properties of the object are:
o name - column name
o table - name of the table the column belongs to, which is the alias name if one is defined
o max_length - maximum length of the column
o not_null - 1 if the column cannot be

o unique_key - 1 if the column is a unique key

if (!$result) {
