When constructing arrays where you are meddling with fixed width
substrings in a larger file make sure that the array item does not
contain a tab or you will certainly get unexpected results;
$arrBadInfo (
'AMARILLOHOUSE ',
'KJONES HOUSE ', <--- 16 characters wide, or is it?
'DCOLLINSCUSTSVC ',
'LAWTON JCOLEMAN',
};
Both above appear to be 16 characters wide in the editor of your choice
(I am using Zend at the moment). However, if there is a tab between
KJONES and HOUSE, the HOUSE is moved to the right the appropriate number
of characters (or inappropriate as it were) and produce undesired
results. I have been working on this issue since 5 am this morning when
I finally decided to print_r() the array (consisting of 192 elements).
Lo and behold (and slapping my forehead thusly) we saw that there were
tabs in the result. Replacing the tabs with the proper number of spaces
fixed the result.
Actually this tip applies to all strings in which you expect there to be
a fixed width. Beware the tab, especially if you are bring in the data
from a source (cuttin' n' pastin') outside of your editor.
