I created a stream wrapper around the php_writeexcel library found at http://www.bettina-attack.de/jonny/view.php/projects/php_writeexcel/ My code can be seen at http://www.pastebin.com/m7212eaa2 I'm trying to add an option that will allow us to lower or uppercase the column headers we create by calling ftell on the Excel stream but when I do something like... $xls = fopen("xlsfile://../data/measurables.xls","wb"); echo ftell($xls); ...I get 0 returned even though I've hard coded a return of 123 in my stream_tell function (which I did to see if my stream_tell was even being called). Can anyone tell me what I'm doing wrong or suggest another way to "communicate" into the stream wrapper that will be compatible with PHP 4 and 5 on OSX, Linux and Windows?
