Description:
------------
Documentation for array_search() says: "If the third parameter strict is set to TRUE  then the array_search() function will also check the types of the needle in the haystack."

But: if the array contains objects, setting the strict-parameter to TRUE will check for object-identity, not only for equality of type and value.

If the comparison would check for equality of type and value only,
the strict variant would output int(0) in the example below, for $foo and $bar do not differ in type or value.

I suggest to supplement the documentation.

Test script:
---------------
$foo = new stdClass; $foo->foo = 'a';
$bar = clone $foo;

var_dump(array_search($bar, array($foo)));     
var_dump(array_search($bar, array($foo), true));

Expected result:
----------------
If the documentation is right (and array_search() has a bug):
int(0)
int(0)

If the documentation is wrong (and array_search() currently works as expected):
int(0)
bool(false)

Actual result:
--------------
int(0)
bool(false)
