Question

I’m curious, more than anything – is it possible to get a PHP value posted? i.e. $_POST['foo'] via some kind of indexing? i.e. $_POST[0]?

($_POST[0] does not work by the way)

Answer 1

No, it’s not possible: you cannot fetch values from an associative array by numeric indexes (because, as clearly noted in the doc, PHP does not distinguish between indexed and associative arrays).

That’s why some functions (PDOStatement::fetch and its siblings, for example) that return arrays take an additional param to control the ‘type’ of indexes in the array returned: numeric (FETCH_NUM), string (FETCH_ASSOC) or both (FETCH_BOTH, the default value). )

The closest you might get with reindexing:

$myPost = array_values($_POST);
