functions

Is there a way to make a variable available inside a function that was created outside of it, without passing it into the function as a parameter?

Ive got some variables from a database, and i want to be able to use them inside a function.

Thanks in advance.

Its not the best of ideas, but you could use the global keyword.

[code=php:0]
$var = "bar";
function foo();
  global $var;
  echo $var;
}
foo();
[/code]

In order to use a variables that were created outside of the function you'll have to define it as global within the function, which thorpe has provided an example of.

I was told from my teacher that to exstend a function you should make a class so in my teachers option the above code is not good code pratice is that correct.
