It is a bitwise OR operator. This operator is used to set the bits of operands if either a or b or both are set. It means the value of the bit will be set to 1.
|A||B||A | B|
$a | $b
In above example, given two values, a = 3 and b = 10. Then convert both the numbers into binary number i.e a = 0011 and b = 1010. Apply OR (|) operation and compute the value of $a | $b.
This is the logical OR operator. This operator is used to do the OR operation. If either of the bits will be 1, then the value of OR will be 1.
$a || $b
Explanation: Here the values for the variables are set. Check if either of the condition is true or not, since the value of a in the if statement is true as it is set to be 3, the OR operator will execute to be true and ‘1’ will be displayed.
Note The key difference in the working of the two operators and the nature are same. The bitwise OR operator sets the bit value whereas the logical OR operator sets true or 1 if either one of the conditions/bit value is 1 else it sets false or 0.
