Q
What does the following PHP code output?

<?php
$x = '10';
$y = 20;
echo $x + $y;
?>

Answer & Solution

Answer: Option A
Solution:
In PHP, if a string is used in a numeric operation, it will be automatically converted to a number if possible. Therefore, the code will output 30, as $x will be converted to the integer 10, and then added to $y, resulting in 30.
