How to parse .xls version 4.0 (BIFF4)?

Question

PHP

It would be necessary to parse the F-Center price list (Excel 4.0 BIFF4) in PHP.
PHPExcel supports from BIFF5, the rest are also only from BIFF5.
Can you tell me the parser for Excel 4.0 (BIFF4) preferably in PHP?

Answer 1

There are good parsers and generators for Perl on CPAN. For Python, as far as I know, some of them have been rewritten. I haven't seen anything like this for PHP.
