Setting a default integer variable in PHP

Question

In Java when I declare a variable int A; by default it assigns 0 to the variable A. But in PHP if I declare a variable as $A the default value of it sets as null. Instead of assigning it as $A=0; are there any ways available to set a default value as 0 for variable $A, as I did in Java?

Answer 1

You can set its type. Since you don't wana initialize to 0, setting type to integer will do that for you.

<?php

settype($foo, "integer"); 

echo $foo;

?>
