px_get_info

(PECL paradox >= 1.0.0)

px_get_infoReturn 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().
