PHP4 Bug #1824: direct file access still used in places despite I/O abstraction

From: seanw@greymatter.co.uk Operating system: Any PHP version: 4.0 Beta 1 PHP Bug Type: Other Bug description: direct file access still used in places despite I/O abstraction A fairly cursory search of the sources for PHP4b1 reveal that there are a number of places where statements like: fflush(stdout); are being used in spite of the I/O abstraction layer. The solution that I would propose would be a FLUSH() macro that defaults to a function in the Zend output.c module to flush buffered output. A search for stdout reveals these locations. Should error messages be handled through a similar abstraction layer rather than being written direct to stderr??? I am somewhat surprised that Zend appears to provide for output buffering, but doesn't appear to provide for flushing the buffer unless it is destroyed. I have only had time for a cursory examination of the sources so please excuse me if this is incorrect. It concerns me because I have an application where I need to be able to switch output streams many times during run-time, buffering would be useful but only if output can be precisely controlled.
