I use PHP on RHEL 6:
$ php -v
PHP 5.3.3 (cli) (built: Dec  5 2013 07:09:40)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

But as, it's too old, I've tested in a Fedora 20:
$ php -v
PHP 5.5.8 (cli) (built: Jan  9 2014 08:33:30) 
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2013 Zend Technologies

In each case, I have the same behavior:
I create a mixed type array, containing both integers and strings. Then, I want to find the position of one particular element, using array_search().
In the case the element is an integer, array_search() returns the correct answer. However, if the element is a string, array_search() always returns 0, but not FALSE, really 0, the integer.  

php > $ary = array(0, 1, "deux", 3);
php > $pos = array_search(3, $ary);
php > var_dump($pos);
int(3)
php > $pos = array_search("deux", $ary);
php > var_dump($pos);
int(0)
// here, IMHO, $pos should contains 2
// as below, with an array containing only strings
php > $ary = array("zero", "un", "deux", "trois");
php > $pos = array_search("deux", $ary);
php > var_dump($pos);
int(2)



Test script:
---------------
$ary = array(0, 1, "two", 3);
$pos = array_search("two", $ary);
if ( $pos === FALSE )
{
   echo "The problem isn't in array_search()...";
   exit;
}
if ( $pos == 2 )
{
    echo "This is OK :-)".PHP_EOL;
}
else
{
    echo "There is bug or a \"strange\" feature :-(".PHP_EOL;
}


Expected result:
----------------
$pos should contain 2

Actual result:
--------------
$pos contains 0
