note 57393 added to control-structures.declare

In reply to Docey: The breakthrough of hyperthreading (intel p4's) is that the processor can execute 2 threads at once...and they do run parallel through the processor. You are correct, Macs don't support this, because Macs (until recently) have been run on non-intel processors that don't use this technology. Windows does support this, and acts as if there are 2 physical processors, even through their are just 2 logical processors. As a side note, Macs also support multiple physical processors. Operating systems are not written in C++, and they never will be. C/C++/C# also must be translated before it can be executed by the processor(s). Processors use something called binary code/machine language/assembly code (all vary slightly in their definition but they are closely related) when executing data. Operating systems are written in assembly language, which is then converted (kind of) to binary executables that the processor understands. C++ is converted into binary code upon compiling it. Then it can be executed where the processor can understand it. Bringing this back to topic, without looking at the PHP backend, I do not know whether PHP supports multi-threading, though I would imagine it does (totally unsure though). Either way, a hyperthreaded CPU would NOT make any considerable improvement on the time a script is executed in regards to using declare, unless of course an assanine amount of code was executed in the declare statement. ---- Manual Page -- http://www.php.net/manual/en/control-structures.declare.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57393 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57393&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57393&report=yes Search -- http://master.php.net/manage/user-notes.php
