Bug description:string is equals a 0 !?
Description:
------------
// tested both in
// in windows 7 - php 5.2.12.12
// in freebsd 7 - php 5.3.3
// because 'e' equals zero, zero is false and false is not equal to 'e'
var_dump(0 == 'e'); // true
var_dump(false == 0); // true
var_dump(false == 'e'); // false
echo '<hr>';
// this means that when we compare int to string will always be equal?
var_dump(0 == "e"); // true
var_dump(0 == "Bernardo"); // true
what is the meaning of this? I think it should not return true.
Test script:
---------------
<?
var_dump(0 == 'e'); // true
?>
Expected result:
----------------
bool(false)
Actual result:
--------------
bool(true)
