Description:
------------
Using PHP's dbase system cannot understand some columns and yields garbage on a certain .dbf file (http://65.108.181.103/zip.dbf).  

The .dbf was tested successfully with several other programs (OpenOffice.org 1.1.4 and Shapefile Library C).

According to file, .dbf is dbase 3 format:
$ file zip.dbf
zip.dbf: DBase 3 data file (586 records)

To enable dbase support, I used the standard Trustix 2.2 source RPM and included "--enable-dbase".

On a different system with PHP 4.3.10 and Linux 2.4.27 (Redhat 7.3), I verified the problem with dbase_get_record_with_names().  (The function dbase_get_header_info() was not available on this platform.)

Reproduce code:
---------------
$db = dbase_open("zip.dbf",0);

print_r(dbase_get_header_info($db));

if ($db) {
  $record_numbers = dbase_numrecords($db);
  for ($i = 1; $i <= $record_numbers; $i++) {
        $row = dbase_get_record_with_names($db, $i);
        print_r($row);
  }
}



Expected result:
----------------
The dbase_header_info() does not understand some columns and includes garbage (e.g. length field).  Then the dbase_get_record_with_names() has incorrect data.  

Here is output of Shapefile Library C's dbfdump -h on the same zip.dbf.  This output is good.
