Trying to understand the manual regarding variables to solve the
following.

I'm working with Drupal CMS and have a loop to retrieve values that
are normally fetched by using this variable: $node-
>field_screen_1_caption[0]['view']. The loop should run n times,
incrementing that number 1 so next variable is $node-
>field_screen_2_caption[0]['view'].

Here's what I'm trying in my loop to change that number in the
variable using $i:

for ($i = 1; $i <= $number_of_screens; $i++) {
$cap = 'node->field_screen_'.$i.'_caption[0][\'view\']';
print $$cap;
}

Doesn't work obviously. Any suggestions for a PHP amateur.

Thanks,
jj
