This is very unique! First structure: if ($a) {} else { only do this } The above structure does executed 12.77% faster than the second structure below! I had loop it 20 millions time and I got this unique result. Second structure: if (!$a) { only do this } By considering this fact then my programming-script will be written awful if I want to do "only do this". For "CODE CLEANLINESS" and logic purpose I shall use the second structure BUT for "SPEED" purpose I better use the first one. Although the different is not significant (will be differ about 3 seconds after 20 millions loop) but I hope PHP developers take time to review how PHP parse (handle) this kind of structure. Well, I'm not sure this could be happened in C++ or others too. But since I mostly use PHP then this becomes my concern. I wonder what people think about my script if they see that I use the former. I worship the speed above all :) ---- Server IP: 202.67.10.139 Probable Submitter: 61.5.68.57 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.control-structures.php Edit -- http://master.php.net/note/edit/64773 Del: integrated -- http://master.php.net/note/delete/64773/integrated Del: useless -- http://master.php.net/note/delete/64773/useless Del: bad code -- http://master.php.net/note/delete/64773/bad+code Del: spam -- http://master.php.net/note/delete/64773/spam Del: non-english -- http://master.php.net/note/delete/64773/non-english Del: in docs -- http://master.php.net/note/delete/64773/in+docs Del: other reasons-- http://master.php.net/note/delete/64773 Reject -- http://master.php.net/note/reject/64773 Search -- http://master.php.net/manage/user-notes.php
