note 29116 added to control-structures.switch

I did some performance testing comparing a series of if/elseif statements against the switch statement. The system was a Pentium II 266 running the ISAPI version of PHP 4.3 on IIS. This was the code: for ($i = 0; $i < 10000; $i++) { if ($bla == 1) { $bla = 2; } elseif ($bla == 2) { $bla = 3; } elseif ($bla == 3) { $bla = 4; } elseif ($bla == 4) { $bla = 1; } else { $bla = 1; } } for ($i = 0; $i < 10000; $i++) { switch ($bla) { case 1: $bla = 2; break; case 2: $bla = 3; break; case 3: $bla = 4; break; case 4: $bla = 1; break; default: $bla = 1; } } if/elseif took an average of 0.085 seconds. switch took an average of 0.097 seconds. -- http://www.php.net/manual/en/control-structures.switch.php http://master.php.net/manage/user-notes.php?action=edit+29116 http://master.php.net/manage/user-notes.php?action=delete+29116 http://master.php.net/manage/user-notes.php?action=reject+29116
