PHP 7 – Spaceship Operator

In PHP 7, a new feature “Spaceship Operator” has been included. It is used to compare two expression together.

The spaceship operator is a combination of comparison operators and denoted by “<=>”. Spaceship operator performs greater than, less than and equal comparison between two operands.

• Returns -1, when the value of first operand is less than the value of second operand.
• Returns 0, when the value of first operand is equal to the value of second operand.
• Return 1, when the value of first operand is greater than the value of second operand.

Spaceship operator can be used with integers, floats, strings, array or objects etc.
