Get certain value from array

Question

I have an array

Array ( 
  [0] => 
  [12] => Array ( 
    [termimages] => Array ( 
      [0] => 58
      [1] => 57
      [2] => 56 
    ) 
  )
)

My result with print_r from $meta.

How can I set a value "12" from array to variable?

Thanks in advance!

as you can see - there is nothing assigned to 0. And it is what I'm talking about — zerkms

Seems like more key not value. Pardon my lack of knowledge about arrays.

In a loop go: foreach ($array as $key => $value)

So you want to get the key of the first member of an array that is the first member of $meta?

$keys = array_keys($meta[0]);
$key = $keys[0];

You've updated your question:

How to get second key from first array?

I.e., in this case, how to retrieve $meta's second key. The technique is exactly the same as above:

$keys = array_keys($meta);
$key = $keys[1];

(And, if and when array dereferencing comes online, this will be able to be shortened to $key = array_keys($meta)[1];, but alas not yet.)

This one looks like is working $keys = array_keys($meta); $key = $keys[1];

How can I set a value "12" from array to variable?

Since there is no value "12" anywhere, I assume you mean the key "12", which has the value of:

Array ( 
    [termimages] => Array ( 
      [0] => 58
      [1] => 57
      [2] => 56 
    ) 
)

To assign it to a variable simply do:

$variable = $meta["12"];

prints:

print_r($variable);

Array
(
    [termimages] => Array
        (
            [0] => 58
            [1] => 57
            [2] => 56
        )

)
