Question
What will be printed by the below code?
$a = 1;{$a = 2;}echo $a;
Select one:
- a. 1
- b. 2
- c. Both
- d. None
Solution
To determine what will be printed by the code, let's analyze it step by step:
- The code initializes a variable
$awith a value of 1. - Next, there is a block of code enclosed in curly braces
{}. Within this block, the variable$ais assigned a new value of 2. - Finally, the code uses the
echostatement 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
