To determine what will be printed by the code, let's analyze it step by step:

1. The code initializes a variable `$a` with a value of 1.
2. Next, there is a block of code enclosed in curly braces `{}`. Within this block, the variable `$a` is assigned a new value of 2.
3. Finally, the code uses the `echo` statement to output the value of `$a`.

Based on this analysis, the code will print the value of `$a` after the block of code is executed, which is 2.

Therefore, the correct answer is:

b. 2
