Pass values to function without using parameter in PHP?

Question

How can we pass the variable value to function without using any parameter? Once we run the script variable value can be echo within the function.

Why would you want to do that? What's wrong with parameters? — Karl Knechtel

The only solution would be to use a global variable, but I don't really see the need for that. Maybe if you expand your question it would be easier to understand what you are trying to do — nico

You could use the keyword global, although I think you shouldn't. Example:

$a = 'foo';
bar();

function bar(){
    global $a;
    echo $a;
}

Above code will print "foo";

Again, I really think you should not use this and come up with some other implementation that doesn't require the use of global variables.

You can access the value of variable by declaring the variable as global variable.
