(zlib.compression namely) I can add new parameter, deletable or not, to ob_start() for user defined handlers also. Anyone need this?

If zlib.output_compression is enabled and the zlib output compression handler is deleted from php_ob_buffer, output will not be sent. I'll leave the real fix for people who knows about zlib output compression and output buffering. I just need to know nesting level to make my script work as I want. I'll send patch for the new function later. ------------------------------------------------------------------------ [2001-12-02 08:20:20] yasuo_ohgaki@yahoo.com A little update. ob_end_flush() has problem also. ------------------------------------------------------------------------ [2001-11-26 06:16:30] yasuo_ohgaki@yahoo.com I cannot reproduce segfualt, but it seems PHP may segfault with this.
