`<?php $test9 = ($b xor &b)? "true":"false"; ?>`

I have uploaded the changes to the code and still it will not echo?

<?php
    $a = true;
    $b = false;
    
    #test both operands for true (&& = and)
    $test1 = ($a and $a)? "true":"false";
    $test2 = ($a and $b)? "true":"false";
    $test3 = ($b and $b)? "true":"false";
    
    #test either operand for TRUE (|| = or)
    $test4 = ($a or $a)? "true":"false";
    $test5 = ($a or $b)? "true":"false";
    $test6 = ($b or $b)? "true":"false";
    
    #test for single operand is TRUE 
    $test7 = ($a xor $a)? "true":"false";
    $test8 = ($a xor $b)? "true":"false";
    $test9 = ($b xor &b)? "true":"false";
    
    #invert values ( ! = NOT )
    $test10 = ( !$a )? "true":"false";
    $test11 = ( !$b )? "true":"false";
    
    $result  = "AND Operand - 1:$test1 2:$test2 3:$test3<br/><br/>";
    $result .= "OR Operand - 1:$test4 2:$test5 3:$test6<br/><br/>";
    $result .= "XOR Operand - 1:$test7 2:$test8 3:$test9<br/><br/>";
    $result .= "NOT Operand - 1:$test10 2:$test11";
    
?>

You're testing with the ternary operator. Its syntax is:

(condition) ? (true event) : (false event)

It looks like you're using a comma instead of a colon in your code.
