PHP Complex If Else Statement

Question

I am using Wordpress and it has code like this:

<?php  
    if (is_user_logged_in())   {   
?>

I want to add to it another set of if statements that check for a variable. I don't know the correct syntax but in plain English I want to say, "if users are logged in and $string1 or $string2 is empty…"

Please assist.

  if ( is_user_logged_in() && (empty($string1) || empty($string2)) ) {

if you need only one string to be empty but not both. use

  if ( is_user_logged_in() && (empty($string1) ^ empty($string2)) ) {

I dont even know what the heck the ^ does in PHP. Please explain. Is that xor?

if (user_is_logged_in() AND (strlen($str1) == 0 OR strlen($str2) == 0))

I will note that this will work if BOTH str1 and str2 have a zero length. If the variables may not be set, as opposed to having zero length use isset instead of strlen() == 0.

if (user_logged_in() && (empty($string1) || empty($string2))

This requires the user_logged_in() call to return true. At least one of $string1 or $string2 needs to be empty.
