passing POST array to php function

Question

Can i pass the entire POST array into a function and handle it within the function?

such as

PostInfo($_POST);


function PostInfo($_POST){
    $item1

The $_POST-array is an array like every other array in PHP (besides being a so-called superglobal), so you can pass it as a function parameter, pass it around and even change it (even though this might not be wise in most situations).

Regarding your code, I'd change it a bit to make it more clear:

PostInfo($_POST);

function PostInfo($postVars)
{
    $item1 = $postVars[0];
    $item2 = $postVars[1];
    $item3 = $postVars[2];
        //do something
    return $result;
}

This will visibly separate the function argument from the $_POST superglobal. Another option would be to simple remove the function argument and rely on the superglobal-abilities of $_POST:

PostInfo();

function PostInfo()
{
    $item1 = $_POST[0];
    $item2 = $_POST[1];
    $item3 = $_POST[2];
        //do something
    return $result;
}
