Functions and Variables

[Anon]

Is there any way to have a function inherit previously defined variables? for example...

this won't work:

<?
$firstname = 'John';
function make_fullname ($var) {
$fullname = "$firstname $var";
return $fullname;
}
$lastname = 'Smith';
$test = make_fullname ($lastname);
echo "$test";
?>

but this will:
<?
function make_fullname ($var) {
$firstname = 'John';
$fullname = "$firstname $var";
return $fullname;
}
$lastname = 'Smith';
$test = make_fullname ($lastname);
echo "$test";
?>

Devin,

You can either declare the variable global within your function, or build a class:

class test {

var $one;
var $two;
var $three;

function test($one = 1, $two = 2, $three = 3) {

$this->one = $one;
$this->two = $two;
$this->three = $three;
}
}

In this example, the function test() is the class constructor and sets the default values of the variables. Those values can be over-ridden by passing values into the class instantiation. The variables are then returned into the classes global scope and can be accessed by any class method using the "$this->var_name" notation. HTH,
