If statment question

[Napster]

If I make a variable outside an If statement, will it still work inside it. And if I make an variable inside the if statement, can i echo it later on in the code outside the if statment.

Try it and see...?
(The answer, by the way, is yes; for the first bit, if you couldn't use a variable inside an if statement that was given a value outside it, you wouldn't be able to test variables; for the second, you wouldn't be able to use the results of an if statement, making the statement more or less useless.)

I think you're misunderstanding the "concept" of the IF statement.

It sort of works like this,

• Whatever you specify inside IF(), is basically checked to see if it is true, such as:

if($name == 'Sharif')

You probably already know this (or you might not), but if you wanted to check if the variable $name was Sharif or not, and you want to display a certain message if it IS Sharif, you would do this:

if($name == 'Sharif') //If the name is Sharif
{
     echo 'Eureka, it is you!';
}
else //Otherwise ..
{
     echo 'Ew, who are you?';
}
