Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip Works fine here. Previous Comments: ------------------------------------------------------------------------ [2006-03-15 17:39:47] astur103 at hotmail dot com Just a comment. I think that an important note. There are 8 consecutive queries to compress_gz function. 1.- Before 5.1.2 (Win32), I had a usleep(100000) between these 8 queries. 2.- Now I have tested that need a usleep(200000) to get that the chunk_split works fine, or at least, the combination of chunk_split(base64_encode(gzcompress, 1))) I hope this helps. Thanks Mapg ------------------------------------------------------------------------ [2006-03-13 16:24:37] astur103 at hotmail dot com Maybe problem is originated on base64_encode or gzcompress funtions, or ZLIB library. Take also in consideration that I am using level 1 of compression. With previous PHP versions, these functions worked finely, and always. Now with 5.1.2 and in my system, sometimes this bug happens.

Later, works fine. Reproduce code: --------------- This is the used function: function compress_gz($string, $level = "1") { $final_string = ""; IF(!empty($string)) { $final_string = chunk_split(base64_encode(gzcompress($string, $level))); } return $final_string; unset($string); unset($final_string); } Expected result: ---------------- I guess that something like this ... ---- LAST 3 LINES OF STRING --- 0r5uCiYhgApgyg3dCkwmwrauUwVphDguNk2YXJFHqWtjYBAbJjL9iS4X14tgmvRNyD6ef+L3Ve3y 5eLawo1+GJjEDVylt2st73hav2fuh90XV7iJbHVZexbnfz9M2d8Yszv8AKlPYUQ== ---- END ---- Actual result: -------------- ---- LAST 3 LINES OF STRING --- 0r5uCiYhgApgyg3dCkwmwrauUwVphDguNk2YXJFHqWtjYBAbJjL9iS4X14tgmvRNyD6ef+L3Ve3y 5eLawo1+GJjEDVylt2st73hav2fuh90XV7iJbHVZexbnfz9M2d8= Yszv8AKlPYUQ== ---- END ---- ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36720&edit=1
