note 50404 added to function.gzwrite

I have question. i have simple function to do basic debug logging ie: function do_log($log_string) { $fp = gzopen("log.gz","a") gzwrite($fp, $log_string, strlen($logstring)); gzclose($fp); } Function do_log is called periodically when we need to log something, all works fine, it appends a line to a log file, but length of log.gz is almost that same or even bigger than original file size. What can be done to have better efficiency. I tried to use gz functions to save hdd space. ---- Manual Page -- http://www.php.net/manual/en/function.gzwrite.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50404 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50404&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50404&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50404&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50404&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50404&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50404&report=yes Search -- http://master.php.net/manage/user-notes.php
