A bit B inary dig IT is the basic unit of information stored in the computing system that exists in two possible states, represented as ON or OFF. In a computer system, the ON state considered as 1 and OFF state considered as 0.

These states can be compared with two states of a flip-flop, two states of an electric switch ON and OFF e. These two values 0 and 1 are called Binary digit and these digits are in a specific number system, that is BINARY number system which constructs upon the base of 2. In decimal number system, a number construct upon the base of Let us see how a decimal number can be constructed -. The binary number system also follows the same concept.

The only difference is the base is 2 instead of Let us see how a binary number can be converted into a decimal number -. A byte is made up of a sequence of bits. A byte consists of eight bits.

The maximum value of a byte is , so the place value of each bit is set. Here is a Tabular representation of a byte shows how the maximum value of a byte is So referring from our tables above it can be said that the only bit this two share is in the 3rd position on place value 4.

So 4 is returned. View the example of php bitwise AND with one shared bit in the browser. View the example of php bitwise AND with two shared bit in the browser. View the example of php bitwise OR in the browser.

The Xor operator also performs a bitwise comparison in two numeric expressions and sets the corresponding bit in the result. When one and only one of the expression evaluates to true the result is true. View the example of php bitwise XOR in the browser.

If it is BIT SHIFT RIGHT, then each step refers to division by two. So, 8 is multiplied by 2 thrice.

View the advance example of php Bit Shifting right shift in the browser. So, 64 is divided by 2 seven times. While dividing at a certain point we don't have anything left to divide.

Thus the return is 0.
