Can i pass the entire POST array into a function and handle it within the function?
such as
PostInfo($_POST);
function PostInfo($_POST){
$item1 = $_POST[0];
$item2 = $_POST[1];
$item3 = $_POST[2];
//do something
return $result;
}
or is this the correct way of doing this?
Yes. If you are going to name the local variable $_POST
though, don't bother. $_POST
is a 'superglobal', a global that doesn't require the global
keyword to use it outside normal scope. Your above function would work without the parameter on it.
NOTE You cannot use any superglobal (ie
$_POST
) as a function argument in PHP 5.4 or later. It will generate a Fatal error
You can actually pass $_POST to any function which takes in an array.
function process(array $request)
{
}
process($_POST);
process($_GET);
Great for testing.
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;
}
