$_FILES -- $HTTP_POST_FILES [deprecated] — HTTP File Upload variables
An associative array of items uploaded to the current script via the HTTP POST method.
$HTTP_POST_FILES contains the same initial information, but is not a superglobal. (Note that $HTTP_POST_FILES and $_FILES are different variables and that PHP handles them as such)
| Version | Description |
|---|---|
| 4.1.0 | Introduced $_FILES that deprecated $HTTP_POST_FILES. |
Note: This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script. There is no need to do global $variable; to access it within functions or methods.
