It looks like the function extract() would be a better tool for what you're trying to do (assuming it's extract all key/values from an array and assign them to variables with the same names as the keys in the local scope). After you've extracted the contents, you could then unset the entire $post, assuming it didn't contain anything else you wanted.

However, to actually answer your question, you could create an array of the keys you want to remove and loop through, explicitly unsetting them...

$removeKeys = array('name', 'email');

foreach($removeKeys as $key) {
   unset($arr[$key]);
}

...or you could point the variable to a new array that has the keys removed...

$arr = array_diff_key($arr, array_flip($removeKeys));

...or pass all of the array members to unset()...

unset($arr['name'],  $arr['email']);
