Summary: 0 equals any string
Status: Not a bug
Type: Bug
Package: Scripting Engine problem
Operating System: windows 2003
PHP Version: 5.2.6

I see this as the biggest inconsistency:
var_dump(0 == "uno"); // true
var_dump(0 == false); // true
var_dump(false == "uno"); // false
While perhaps not a bug by strict definition, I think it's definitely an error in
design.

Maybe because that's not a bug... "It's not a bug, it's a feature".
Equality (==) and identity (===) are different, if for your use, equality is the
best, just use it then.

I can see that it's no any logical explanation to keep this BUG unfixed! Status: Not a bug
-> why??? It's not funny, so many years past.
I do love to use PHP and like that no needed to define variable types, but this is generic FAIL.
Come one guys, someone need to fix this, please.
My PHP version
PHP 5.3.10-1ubuntu3.5 with Suhosin-Patch (cli) (built: Jan 18 2013 23:45:59)

This is quite ridiculous. Can this 'feature' of PHP *please* be reconsidered?

I don't recall PHP ever behaving that way.
So how do you alter a switch statement to use the identical operator instead of equivalency?
It seems somewhat odd that any text character would be equvalent to integer 0. As I remember the
chart it was something like:
0 == '0' true
0 == '' true
0 == null true
0 == false true
0 == 'text' false
Basically if we are going to treat any string as equivalent to 0, the switch statement becomes
useless when iterating through arrays unless you first strip key names of integer 0.
