Re: [PHP] force download and file size issue
this is what i have exactly in my code... header(Content-Type: application/force-download; name=\$file\); header(Content-Disposition: attachment; filename=\$file \); header(Content-Transfer-Encoding: binary); header(Content-Length: $content_length); readfile($file_fullpath); exit; it works for files upto 10M (same as memory limit) but not above. the paths to file and content length are correct as i have checked them and made comparisons to other files which i can download. is there a problem with this code? i have tried it with win ie 6 and mac ie 5.1.2 and ns 4.7.. same issue cheers christian Rasmus Lerdorf wrote: readfile() reads 8k blocks at a time and dumps them out.
