PHP: Why does 0 == "v2"?

I came across a defect in my software caused by: 0 == "v2" is true

Firstly that seems crazy but I'm sure theres some weird conversion going on. I need a way to compare two values without specific types, i.e.:

0 == "v2" is false

0 == "0" is true

But the === operator will not work in the second case. Is there a reliable way to do this?

loosely typed comparisons... [read all about it](http://www.php.net/manual/en/types.comparisons.php) – Mark Baker Jul 31 '14 at 22:36

To solve the problem you mention, check `(string) $value1 === (string) $value2`. – cmbuckley Jul 31 '14 at 22:39
