Question
Which one is NOT a valid PHP comparison operator?
Question 18
Select one:
- a.
!= - b.
<> - c.
!< - d.
===
Solution
To determine which one is NOT a valid PHP comparison operator, we need to analyze each option:
a. != : This is a valid PHP comparison operator. It checks if two values are not equal.
b. <> : This is also a valid PHP comparison operator. It is an alternative syntax for the != operator and also checks if two values are not equal.
c. !< : This is NOT a valid PHP comparison operator. The correct syntax for checking if a value is not less than another value is using the >= operator.
d. === : This is a valid PHP comparison operator. It checks if two values are identical in both value and type.
Therefore, the answer is c. !<, as it is not a valid PHP comparison operator.
