variables

[Rayn]

Is there a way to include all active / set variables into a function without using global?

I suppose you could make the parameters of your functions be all $POST, $SERVER, etc arrays. you make that the default. Then you'd have to sort through the arrays inside the function. I've never tried it, but I can't think of a reason why it wouldn't accept these arrays.

I more so mean. Like I define the variables

$name
$age
$height
$weight
$etc

but they are all usable within a function without using global.

$name
$age
$height
$weight
$etc

function this() {
echo $name;
}

this(); // outs name variable

?

Do you mean, how do you pass variables to a function without global? Did you read the manual on function()? It's well documented. Just pass the info when you call the function, as you would with any other function.

function dog_cat($catname, $dogname)
{
$out = "$dogname ate $catname! Oh no!";
return $out;
}

echo( dog_cat("ralph", "spot") );

that would return:
spot ate ralhp! Oh no!

that is still defining the variables that will be used within the functions, I need it so all possiable variables will be passed into a function without setting which ones they are.

I don't know of a good way of doing this but here are two ideas that come to mind.

Make all of your variables inside the PHP global array ($GLOBALS[]). Ex:
$name becomes $GLOBALS['name']
$age becomes $GLOBALS['age']
...
function example() {
print($GLOBALS['name'];
print($GLOBALS['age'];
}

Define the variables used in the function global right before you use them. Ex:
$name
$age
function example() {
global $name;
print($name);
...
global $age;
print($age);
}

I know this isn't what you really want but it's the only way I've found how to do this.

The simplest way in the world (I'm using it in a limited fashion for a true PHP-templating system (passing an array instead of running through $GLOBALS).):

$foo = "PHP is easy. Try C++.<br>\n";

function bar ()
{
  foreach ($GLOBALS as $key => $value)
  {
    $$key = $value;
  }

  return $foo;
}

echo bar();

Thank you mate, exactly what I was looking for. 🙂
