Accessing array within an array using a string as the key [duplicate]

Question

Im currently trying to build a validation class in PHP. What im trying to do is match the array of validations required with the $_POST array. My validation array gives the following values which are field names

$validation[0] = “order[0][company]”
$validation[1] = “order[1][company]”
$validation[2] = “order[2][company]”

And so on. The $_POST array looks like this

Array ( [order] => Array ( [0] => Array ( [company] => [link] => [username] => [password] => [comments] => ) [1] => Array ( [company] => [link] => [username] => [password] => [comments] => )

How do I access the value from the post array using the field names given above? I tried $_POST[$validation[0]] but it doesn’t seem to work.

$_POST[$validation[0]], with a pair of brackets instead of parentheses, as you'd access any other array.
