fsync() function
fsync() is a function similar to fflush(), however where fflush() only instructs the application to flush its internal buffers out to the OS, fsync() further instructs the OS to flush its buffers to physical storage, ensuring a completed and persisted write before returning any success. PHP provides plain stream wrappers for most common file system functions inherited from C and is indeed one of few major languages to not provide any interface to fsync. This RFC proposes implementing fsync in core.
