Able to see a variable in print_r()'s output, but not sure how to access it in code

The output of print_r($node) is the following.

[field_pimage] => Array
        (
            [und] => Array
                (
                    [0] => Array
                        (
                            [fid] => 4
                            [alt] => 
                            [title] => 
                            [width] => 1440
                            [height] => 900
                            [uid] => 1
                            [filename] => 200801232112524201.jpg
                            [uri] => public://200801232112524201.jpg
                            [filemime] => image/jpeg
                            [filesize] => 122349
                            [status] => 1
                            [timestamp] => 1351403970

I want to output the [uri]'s value, how should I do it?

 $node->field_pimage->und->0->['uri'];  //but it doesn't work?

You are dealing with arrays, not objects.

So you either need $node->field_pimage['und'][0]['uri'] (if $node itself is an object) or $node['field_pimage']['und'][0]['uri'] (if $node is an array, too)

As it's an array... it should be accessed using...

$node['field_pimage']['und'][0]['uri'];

I didn't down vote but - you need single quotes – Chris Nov 01 '12 at 12:30

you don't **need** single quotes, the performance gain from doing so would be negligible. Do whatever is more readable for yourself – SubjectCurio Nov 01 '12 at 12:40
Ah - I didn't realise there was a preformance gain, just makes it easier to read! I should have phrased it better sorry! ^^ – Chris Nov 01 '12 at 12:44

I always write strings with double quotes if it's possible, this is usual for ppl who started with something like `VB`. And for performance it's impossibly negligible. So as @MLeFevre said `I do whatever is more readable for me` :) – loler Nov 01 '12 at 12:51

Since they are all arrays you can use this syntax;

$node['field_pimage']['und'][0]['uri'];

It's a multidimensional array.

Work down the hierarchy of the array.

$uri = $node['field_pimage']['und'][0]['uri'];

print($uri);
