how can I print out data from function?

[gca07738]

function aaa() {
$a=1;
return $a;
}
echo aaa();

==>show: 1

function aaa() {
$a[0]=0;
$a[1]=1;
return $a;
}
echo aaa();
==>show: array

how can I print out $a[0] and $a[1] ?

[cosminb]

print_r(aaa());
//or
var_dump(aaa());
//or
$result = aaa();
if (is_array($result))
{
  for ($i=0;$i<count($result);$i++)
  echo $result[$i]
}
else
{
  echo $result; //that's unless your function doesn't return a struct
}
