[php]$_post

[The Red Guy]

What does it refer to? And why is it preferred (also includes $_GLOBAL and on) :)

[keith]

<form action="index.php" method="post">
<input type="text" name="subject" value="">
<input type="submit" name="submit" value="Submit">
</form>

on the next action, you'd need to recall the subject:

$_POST['subject'];

it is also the same as

$HTTP_POST_VARS[]

$_POST['string'] is a superglobal array. Remember when you write $data = $_POST['string'] , $data is not a variable.
//Remember, php is case sensitive so $_post won't work.
