Function returning an array ??

[Texas Guy]

Not getting what I expect when I try to return an array from my
function. See sample below.

function test()
{
$myArray["one"] = 1;
$myArray["two"] = 2;
return $myArray;
}

$thisArray = test();
foreach($thisAr ray as $thisKey -> $thisVal)
{
echo($thisKey . " is " . $thisVal . "<br>");
}

// The output:
// Should Be: But Is:
// one is 1 Object is
// two is 2 Object is

What's up? How do I pass back an array from a function? I tried
passing it back as an &argument but that doesn't work either.

Output is in fact:


Notice: Undefined variable: thisVal in D:\public_html\ test.php on line 10

Notice: Undefined variable: thisVal in D:\public_html\ test.php on line 12
Object is

Notice: Undefined variable: thisVal in D:\public_html\ test.php on line 10

Notice: Undefined variable: thisVal in D:\public_html\ test.php on line 12
Object is

Having error_reporting set to E_ALL gives you more clues to work with.

Your problem is the loop, you're using the wrong operator:
[color=blue]
>foreach($thisA rray as $thisKey -> $thisVal)[/color]

Should be:

foreach($thisAr ray as $thisKey => $thisVal)

-> is object access, => is for 'key => value' in foreach and array
construction.

Output with => is:

one is 1
two is 2

^^

Mind your syntax: You're trying to access an element in an Object here.
try "=>" instead and it works.
