Why use array("$new_cat",...,"$assigned_by");
Loose the quotes: array ($new_cat,...,$assigned_by);
You don't need to use implode(). Just return the array. In the
calling function you can then get the results in two ways:
$results = assign(); /* $results is an array */
or
list ($new_cat,...,$assigned_by) = assign();
If you want a better answer on what is going wrong, you'll need to
send some more code. Eg the code that you've now replaced by .
It might just be that the error is in that part.

Re: [PHP] strings in a function return
Im beginning to think that functions aren't all that cracked up to be.
I may as well go back to my old "non function" way of coding.
I was displaying the form in the function because the application Im
using currently displays forms in functions. Ill try and see what I can
do with this new found knowledge called 'functions'.

Here is a snippet example.
function assign() {
global $adminurl, $string;
top();
if ($string) {
$data = explode ("|", $string);
echo "$data[0]";

$array = array("$new_cat,$assigned_to","$job","$assigned_by");

Why are you putting the form inside the function? There surely must be a
better way to achieve what you want (which is not clear from the snippet).

Re: [PHP] strings in a function return
top(); is a function that displays a menu, that works.
is where the form goes.
In its current setup less the array/implode/explode/foreach loop
I can get it to echo 'a' return that I specify. But its no good, when I
have 7 seven fields in the form to process.

Hrm - undefined function top()

But the rest of it returns what I would expect - a comma followed by two
| - given that I don't have the values referenced in the array. And you
won't either, as they aren't global and aren't passed as parameters.

Hey all. I just started venturing into functions. I have a function

strings back after the submit. Im tryed a return statement at the

Is it even possible to return mulitple values from a function??

Thanks You can only return one variable from a function, but that variable can be an array. This is probably obvious, but you are assigning the result of the function to a variable?
