Which data type will the $a variable have at the end of the following script?

<?php
$a = “1”;
echo $a;
?>

A. (int) 1
B. (string) “1”
C. (bool) True
D. (float) 1.0
E. (float) 1

Answer B is correct.

When a numeric string is assigned to a variable, it remains
a string, and it is not converted until needed because of an operation that
requires so.
