Call variable inside array element

Question

Is it possible to read array element using variable? I'd like to set $vid in one place depending on the configuration, and then use multiple times i.e. $detailrow["customfields1"]; I want to do this:

$vid = 1;
$detailrow["customfields$vid"];

But no response.

Tried:

$detailrow["customfields{$vid}"];
$detailrow['customfields'.$vid];

but result is the same.

How about an intermediate step like `$newKey = "customfields" . $vid` and then `$detailrow[$newKey]`? — DevlshOne, Jul 10 '13 at 12:17
use print_r() to check whether there is value associated to the key or not.I think that could be the problem — saran banerjee, Jul 10 '13 at 12:18
All three of your tried methods ought to work fine. Check your raw data. — Maxim Kumpan, Jul 10 '13 at 12:20
Ok, it was array depth misunderstanding. Works fine now. Thanks for quick replies! — jakubplus, Jul 10 '13 at 12:20
what u tried is correct but does your array have the key??just see that by using `print_r` — Arun Killu, Jul 10 '13 at 12:22

Of course you can do this:

$tmp=array("name" => "foo", "bar" => "name", "field1" => "value1");

You could then do sth. like

echo $tmp["name"];

will print 'foo'

echo $tmp[$tmp["bar"]];

will also print 'foo'

Or

$i=1;
echo $tmp["field".$i]

will print 'value1'
