PHP: Using Variables in Functions?

Question

Hi,

I am new to PHP. Can anyone provide me with a quick example of how to set a variable that a function can use (any function would be good).

Thanks.

Answer 1

$var = "something";

function bla_bla() {
global $var;

echo $var; // this will echo "something"
};

?>

Notice the "global $var;" line? That tells the function that whenever you use that variable in the function, it will look for it in the global scope, outside the function :)
