The Ds\Set::xor() function is an inbuilt function in PHP which is used to create a new set which contains the value either in the first set or second set but not both.
Syntax:
Ds\Set public Ds\Set::xor ( Ds\Set $set )
Parameters: This function accepts a single parameter $set which is used to hold the set of values.
Return Value: It is used to return a set which contains the xor of the current set with another set.
Below programs illustrate the Ds\Set::xor() function in PHP:
Program 1:
<?php // Declare a new set $a = new \Ds\Set([1, 3, 5]); // Declare a new set $b = new \Ds\Set([2, 3, 6]); // Print the xor of both set echo("xor of both set is: \n"); print_r($a->xor($b)); ?> |
Output:
xor of both set is:
Ds\Set Object
(
[0] => 1
[1] => 5
[2] => 2
[3] => 6
)
Program 2:
<?php // Declare a new set $a = new \Ds\Set([2, 3, 6, 7, 8]); // Declare a new set $b = new \Ds\Set([2, 3, 5, 8, 9, 10]); // Print the xor of both set echo("xor of both set is: \n"); var_dump($a->xor($b)); ?> |
Output:
xor of both set is:
object(Ds\Set)#3 (5) {
[0]=>
int(6)
[1]=>
int(7)
[2]=>
int(5)
[3]=>
int(9)
[4]=>
int(10)
