The $_POST variable is an array already, so if you want to append it to another array, you can use the array_merge function to do so. For example:
$foo = array('alpha', 'bravo', 'charlie');
$bar = array_merge($foo, $_POST);
If there were two variables posted, one called "blah" with a value of 7 and one called "snarf" with a value of "snoo", then the $bar array would now be:
Array(
0 => 'alpha',
1 => 'bravo',
2 => 'charlie',
'blah' => 7,
'snarf' => 'snoo'
)

Unsetting a variable is entirely different -- performing a variable unsetting causes the variable to have a value of NULL, as if it was never set.
