From: Operating system: no matter PHP version: 5.4.0RC6 Package: *Programming Data Structures Bug Type: Feature/Change Request Bug description:Optimization
Description:
------------
First sorry for my English, it's not perfect.
In this case
if($a==1 and $b==2)
{
echo 'hello there';
}
I think $b==2 checking is unnecessary if $a==1 it's not true.
PHP will be faster.
