px_get_info
(PECL paradox:1.0-1.4.1)
px_get_info — Return lots of information about a paradox file
Description
array px_get_info
( resource $pxdoc
)
Parameters
-
pxdoc
-
Resource identifier of the paradox database
as returned by px_new().
Return Values
Returns an associated array with lots of information about a paradox
file. This array is likely to be extended in the future.
-
fileversion
-
Version of file multiplied by 10, e.g. 70.
-
tablename
-
Name of table as stored in the file. If the database was created
by pxlib, then this will be the name of the file without the
extension.
-
numrecords
-
Number of records in this table.
-
numfields
-
Number of fields in this table.
-
headersize
-
Number of bytes used for the header. This is usually 0x800.
-
recordsize
-
Number of bytes used for each record. This is the sum of all
field sizes (available since version 1.4.2).
-
maxtablesize
-
This value multiplied by 0x400 is the size of a data block in bytes.
The maximum number of records in a datablock is the integer part of
(maxtablesize * 0x400 - 8) / recordsize.
-
numdatablocks
-
The number of data blocks in the file. Each data block contains a
certain number of records which depends on the record size and the data
block size (maxtablesize). Data blocks may not necessarily be
completely filled.
-
numindexfields
-
Number of fields used for the primary index. The fields do always start
with field number 1.
-
codepage
-
The DOS codepage which was used for encoding fields with character data.
If the target encoding is not set with
px_set_targetencoding() this will be the encoding for
character fields when records are being accessed with
px_get_record() or
px_retrieve_record().
