With PHP it is quite easy to modify SWF files. The compression algorithm of SWF is Zlib. SWF default compression level is 6, at least Flash CS2 uses this level. I tested this by uncompressing compressed SWF file and then compressed the contents with levels 0-9. With level 6, the contents of files were identical. Maybe it can be whatever else, but when trying to compare files at hex level or compare filesizes, it is easier to use the same level. ---- Server IP: 80.81.171.181 Probable Submitter: 84.249.93.137 ---- Manual Page -- http://www.php.net/manual/en/function.gzcompress.php Edit -- https://master.php.net/note/edit/90140 Del: integrated -- https://master.php.net/note/delete/90140/integrated Del: useless -- https://master.php.net/note/delete/90140/useless Del: bad code -- https://master.php.net/note/delete/90140/bad+code Del: spam -- https://master.php.net/note/delete/90140/spam Del: non-english -- https://master.php.net/note/delete/90140/non-english Del: in docs -- https://master.php.net/note/delete/90140/in+docs Del: other reasons-- https://master.php.net/note/delete/90140 Reject -- https://master.php.net/note/reject/90140 Search -- https://master.php.net/manage/user-notes.php
