- != operator
- The inequality operator (!=) is the logical opposite of the equality operator. It means “Not Equal” and returns true where equality would return false and vice versa.
- Like the equality operator, the inequality operator will convert data types of values while comparing.
- For example 1 != ‘1’ will return false since data type conversion take place so 1 and ‘1’ are considered equal.
- !== operator
- The strict inequality operator (!==) is the logical opposite of the strict equality operator. It means “Strictly Not Equal” and returns true where strict equality would return false and vice versa.
- Strict inequality will not convert data types.
- For example 1 !== ‘1’ will return true since 1 is an integer and ‘1’ is a character and no data type conversion take place.
- What is the difference between the | and || or operator in php?
