Description:
------------
When you have an array with boolean values, then in_array will always return true.

Reproduce code:
---------------
print in_array("test it", array(true, true, "sdsd" => true))

Expected result:
----------------
should return false

Actual result:
--------------
true

Use the 3rd optional parameter (for strict search) which makes  
in_array() to check the type too. NOT a bug.

Right, it works with 3rd parameter, but it is not the point - is string "test" equal to boolean "true" ? Even if we are not comparing variable types, then "test" is not equal to "1". For example, I have an array with strings, integers, boolean - I'm looking for any "123" value - I don't care if this is an integer or string - the value is important. In this case, I can't use in_array with 3rd parameter, because it will not find all all correct values. 

examples:

in_array('232', array(232, '232', true))
this will return true - correct

in_array('232', array(232, true), true)
this will return false - correct

in_array('232', array(233, '233', true))
this will return true - wrong

In my opinion this is not correct behavior...

sniper@php.net, can you describe the reasoning behind this behavior? Currently, I'm inclined to agree with Marek that this is bug-like behavior. Thank you. Mike.
