Of course there is also a method to export the > data in BibTex Format again it is called "bibTex". The code for the parser is very naive. Seems like you did not test it with a variety of BIBTEX input. For one, you cannot rely on the field data being on just one line. That is an artificial restriction you are putting in your code and does not exist in the original Bibtex spec. Your code fails in many sample files known in the literature. Also, it seems like the code is just the start of a Bibtex parser, because it does not do any validation of the entries being added, or parsed (see example below). It might be nice to have some sort of encapsulation and validation of entries, but this could be a new package (Structure_BibTex perhaps?), so one could do: $art = new Structure_BibTex_Article(); $art->setAuthor(array('Random Nerd', 'Unix Foggie')); ... etc. In any case, take a look at: ftp://sunsite.unc.edu/pub/packages/TeX/biblio/bibtex/distribs/doc/btxdoc.tex (or the similar document in the tetex distribution) http://en.wikipedia.org/wiki/BibTeX http://www-static.cc.gatech.edu/classes/RWL/Projects/citation/Docs/UserManuals/Reference_Pages/bibtex_doc.html http://www.ecst.csuchico.edu/~jacobsd/bib/formats/bibtex.html From the second URL we can take an example that will break your code: [ex.bib] @Book{abramowitz+stegun, author = "Milton Abramowitz and Irene A. Stegun", title = "Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables", publisher = "Dover", year = 1964, address = "New York", edition = "ninth Dover printing, tenth GPO printing", isbn = "0-486-61272-4" } when run with your code: $ex = new File_BibTex(); $ex->loadFile('ex.bib'); $ex->parse(); print_r($ex->data); gives the incorrect: Array ( [0] => Array ( [type] => Book [cite] => abramowitz+stegun [author] => Array ( [0] => Milton Abramowitz [1] => Irene A. Stegun ) [title] => Handbook of Mathematical Functions wit [Formulas, Graphs, and Mathematical Tables", publisher] => Dover [year] => 1964 [address] => New York [edition] => ninth Dover printing, tenth GPO printing [isbn] => 0-486-61272-4 ) ) -- Jesus M.
