The value of a class constant in PHP cannot be changed once it is ______.
- defined

- assigned
- declared
The value of a class constant in PHP cannot be changed once it is assigned. Once a constant is defined with a specific value, it remains the same throughout the execution of the script. Constants are considered as read-only values. It's important to note that attempting to modify a constant's value will result in a runtime error. To maintain the immutability of constant values, it is recommended to define them with the desired value and avoid any attempts to modify them later.
