Solution

To analyze the code provided:

  1. Understanding Variable Case Sensitivity:

    • In PHP, variable names are case-sensitive. This means $var and $VAR are considered two distinct variables.

  2. Variable Assignments:

    • $var is assigned the value 'a'.
    • $VAR is assigned the value 'b'.

  3. Concatenating Variables:

    • The echo statement is used to output the value of the variables. In this case, it prints the value of $var followed by the value of $VAR.

  4. Output Evaluation:

    • The output will concatenate the values of both variables: first, $var which is 'a', and then $VAR which is 'b'.

Final Answer

The output of the code will be ab. Thus, the correct choice from the options is: d. ab.
