Description:

Hi there,

I am having a problem with boolean variables stored in the cache.  They are converted to strings, making it impossible to check them against type when comparing (===) the results.

Thanks

Michael

Reproduce code:
---------------
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");

$version = $memcache->getVersion();
echo "Server's version: ".$version."<br/>\n";

$tmp_var = true;
$tmp_var2 = false;


$memcache->set('key1', $tmp_var, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";

$memcache->set('key2', $tmp_var2, false, 10) or die ("Failed to save data at the server");
echo "Store data in the cache (data will expire in 10 seconds)<br/>\n";


$get_result = $memcache->get('key1');
echo "Data from the cache:<br/>\n";
var_dump($get_result);

$get_result = $memcache->get('key2');
echo "<br />Data from the cache:<br/>\n";
var_dump($get_result);

Expected result:
----------------
Server's version: 1.1.12
Store data in the cache (data will expire in 10 seconds)
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
bool(true)
Data from the cache:
bool(false)

Actual result:
--------------
Server's version: 1.1.12
Store data in the cache (data will expire in 10 seconds)
Store data in the cache (data will expire in 10 seconds)
Data from the cache:
string(1) "1"
Data from the cache:
string(0) ""
