How can I get the value in this array?

Question

I cannot figure out getting the string 'foo' printed from an array. How can I just print the value in 'tags'?

print_r(array_values($res));

Array
(
    [0] => Array
        (
            [tags] => foo
        )

)

Why are you using `array_values`? What does it look like without that? — Don't Panic, Jun 07 '17 at 20:30
[The PHP documentation](http://php.net/manual/en/language.types.array.php#language.types.array.syntax.accessing) should be helpful. — Don't Panic, Jun 07 '17 at 20:31
`$res` may not actually have a 0 index. Or it might. No way to tell since it's been run through `array_values`. — Don't Panic, Jun 07 '17 at 20:35

Arrays work in depth. You can have array that store arrays and so on. If:

$res = array ( 0 => array ( ['tags'] => 'foo' ) );
echo $res[0]['tags']; // foo

does that make sense?

Also, be careful when using Array and array
