Variables to carry over from function to function

[jaykup]

Simple question: If i had a code like this, how can I tell FunctionTWO to use a set variable from FunctionONE with out creating the variable outside the two functions

Example:

function FunctionONE()
{
     $color = "red";
}

function FunctionTWO()
{
     echo "The color is $color";
}

// This will display "The color is " instead of "The color is red"
// How can I change it?
FunctionTWO()

Well this will do the trick althought I wouldnt do things this way:

function FunctionOne() {
        global $color;
        $color = 'red';
}

function FunctionTWO() {
        global $color;
        FunctionOne();
        echo "The color is $color";
}

FunctionTwo();

I would do this in an obejct oriented manner:

Class Color {
        var $color = 'red'; // set default color

    function SetColor($col) {
            $this->color = $col;
    }

    function GetColor() {
            return $this->color;
    }
}

$col = new Color();
$col->SetColor('blue');
echo 'The color is '.$col->GetColor();
