Bitwise AND operator in PHP (&)
July 28, 2022 ‐ 1 min read
For the bitwise AND operator in PHP the ampersand sign is used (&). Together with the other bitwise operators in PHP, the AND operator allows us to perform logical operators.
The AND operator only results in true if both operands are true, or 1 instead of 0.
The truth table of the AND operator in PHP looks as follows:
<?php
echo true & true # => true
echo true & false # => false
echo false & true # => false
echo false & false # => false
