Unary Operators in PHP

In PHP, Unary operators are operators that work on only one operand. There are several Unary operators available in PHP, including:

Unary plus (+): It is used to convert an operand to a numeric value, and it is denoted by the plus sign (+).
Unary minus (-): It is used to negate an operand and is denoted by the minus sign (-).
Increment (++): It is used to increase the value of an operand by one.
Decrement (–): It is used to decrease the value of an operand by one.
Logical not (!): It is used to reverse the logical value of an operand.
Bitwise not (~): It is used to invert the bits of an operand.

These operators are often used in PHP programs to perform various operations such as arithmetic, logical, and bitwise operations.
