Question

Is there any way to access POST data by index, rather than accessing it through keys? I’d like the following code to work:

for($x = 0; $x < count($_POST); $x++)
    echo $x . ": " . $_POST[$x];

(Yes, I know that count in the loop is bad, just using it for simplicity)

The problem is that apparently I can’t access the $_POST variable by index, it has to be accessed by key. The reason I can’t use keys is because I’m going to have variable form data, so there could be more or less in the POST, so I need to be able to loop through a variable number of keys, with variable names.

Any help is appreciated!

EDIT: To clarify, I was confused because I had previously assumed that PHP arrays behaved almost like C++ enumerations.

Use foreach() instead, it also works on numeric arrays.

foreach ($_POST as $key=>$val)
    printf("%s: %s\n", $key, $val);
