The value of a class constant in PHP cannot be changed after it is defined. Once a constant is assigned a specific value, it remains the same throughout the execution of the script. Constants are considered as read-only values. 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.
