I've written a simple recursive function to convert trees like <*a* <*b*, *c*>, <*d*>> into PHP arrays like the corresponding one as generated by array (a, array (b, c), d) The resulting array construct is directly usable. Feel free to include the function in your own sources and modify it at will. I hereby release it under the bugroff license available from http://www.geocities.com/SoHo/Cafe/5947/bugroff.html this is the code: function free_to_array ($str) { $i = 0; while ($cursor < strlen ($str)) { while ( ($c = substr ($str, $cursor, 1)) == " " || $c == "\n" || $c == "," || $c == ".") $cursor ++; $match = $c; if ($c == "<") $match = ">"; $end = strpos ($str, $match, ++ $cursor); $level[$i] = substr ($str, $cursor, $end - $cursor); if ($c == "<") $level[$i] = free_to_array ($level[$i]); $cursor = $end + 1; $i ++; } return $level; } and a practical application example: xml_open ("test", "<*language*> <*JavaScript*>"); creating element/value pairs for use in XML-like documents without the syntax overhead of nested calls to arrays.
