PHP is case sensitive. Additionally, quotes, or the absense of quotes,
can change the context. I bring this up because the example you have
above, $_post[sender_email] contains two errors:
* $_post will likely be empty, whereas the PHP superglobal $_POST will
likely contain the data you're looking for ;-)
* $_post[sender_email] refers to the value in the $_post array returned
by an array key that is the same name as the value of the constant
sender_email. You almost certainly were actually meant
$_POST['sender_email'] (note the quotes), which would refer to the
value associated with the array key 'sender_emaail' in the $_POST
array.
You should probably do some reading in the introductory chapters of the
PHP manual, specifically the variables section:
