Q
What will be the output of the following PHP code?

<?php
$x = 10;
echo ++$x;
?>

Answer & Solution

Answer: Option B
Solution:
The code uses the pre-increment operator (++$x), which increments the value of $x by 1 and then returns the new value. Therefore, the output will be 11, as ++$x increments $x from 10 to 11 and then prints it.
