Array available to function??

Anon

Hello.

Here is simple question with probably a simple answer. Forgive me for asking and not trying it on my own, but I'd rather not mess up what I have going!!

Are arrays declared outside a function, available in functions? Or do you have to pass in the Array like u do a variable? I'm trying to get in the habit of using the same code in a function to avoid having duplicate code.

Example:

$array[1] = "rahh";
$array[2] = "rahh";

function test() {
echo $array[1];
echo $array[2];
}

Will this work? Thanks.

Oh I also meant to ask if the $argv (command line arguments) would also be available inside a funtion. Thanks.

unless you declare the variables/arrays as global, they will not be available in your function. Check out what the manual has to say about variable SCOPE:

Thanks for the reply.

When I got around to trying it, passing the array into the function as an argument worked. I thought I tried making it global and it didnt work but I could be wrong.

For example this would work

$array[0] = "thing"
$array[1] = "thing"

function myfunction($array) {
$count = count($array);
return $count;
}

$count = myfunction($array);
