Bug description: Memcache using references where none exists
Description:
------------
Memcache somehow obtains a reference where none exists. In the example, I
set $clave to a string, set $keyword to a copy of $clave (since $clave is a
string, I'm assuming it internally is copied by value, not reference, as
per the docs?), and then do something with $clave. At the end of this
mucking, $keyword is changed, replacing a space with an underscore.
The problem does NOT occur if I say $keyword = substr($clave, 0); instead
of $keyword = $clave, so I'm assuming it's somehow obtaining a reference?
(The script starts and ends at the <?php and ?> sections, there's nowhere
that says global $keyword or anything).
The memcached server version is 1.2.1, running on Apache 2.0.53.
Reproduce code:
---------------
<?php
$a = memcache_pconnect("192.168.1.252", 11211);
$clave = "abc 123";
$keyword = $clave;
echo "K: ".$keyword."<br/>";
$a->get($clave);
echo "K: ".$keyword."<br/>";
?>
Expected result:
----------------
K: abc 123
K: abc 123
Actual result:
--------------
K: abc 123
K: abc_123
