Beginners PHP Question: What the difference between $_POST and $_FILES?

Beginners PHP Question: What the difference between $_POST and $_FILES?

PHP.net says:

$_POST is an associative array of variables passed to the current script via the HTTP POST method

$_FILES is an associative array of 开发者_如何学编程items uploaded to the current script via the HTTP POST method

Could anyone explain what this means in practical terms?

Both $_POST and $_FILES are so called in php "superglobals". They are predefined variables(arrays), which means they are available in all scopes throughout a script. There is no need to declare them to access them within functions or methods.

$_POST contains all the data from forms (except files)

$_FILES contains all files sent to server via forms (only from <input type="file" />)

$_POST and $_FILES are called 'superglobals'. $_POST contains the data from the form without displaying it in the url address. So it's safe in posting data. But for files you have to use $_FILES, because files can not be posted using $_POST.

Hope it will work for you.
