First you can tell if it is set yet with isset($myvar). Second if it is not set it treats it like null. And what do you mean "if it doesnt yet EXIST"? You created a name and you haven't assigned value to it yet. What would you expect it to be besides null?Quote:
OK so how the hell does it process it if it doesnt yet EXIST (see this type stuff makes me NUTS!)
You really don't want to know. And I doubt many PHP programmers know either. But it is internally consistent. Try this to see what it's doing:Quote:
$myString = "hello";
whats the result of that mess?
Honestly, this stuff is just language trivium. If small changes like the many listed in this thread actually bother you then stick with what you are confortable with.Quote:
$s = 'yyy';
