Description:

From manual page: http://www.php.net/memcache.pconnect#Return Values
---

In fact, Memcache::pconnect(), just like Memcache::connect() returns a mixed type.
It will return a Memcache object if the connection is successful or a boolean false if the connection fails. Also a notice and an error will be outputted.

Test script:
---------------
<?php

// memcached is running
$memcache_obj1 = memcache_pconnect("memcache_host1", 11211);
var_dump($memcache_obj1);

/*
will output:
object(Memcache)#3 (1) {
  ["connection"]=>
  resource(6) of type (memcache connection)
}
*/

// memcached is stopped
$memcache_obj2 = memcache_pconnect("memcache_host2", 11211);
var_dump($memcache_obj2);


/*
will output:
PHP Notice:  memcache_pconnect(): Server memcache_host2 (tcp 11211) failed with: Connection refused (111) in /home/jdoe/memcache-test.php on line 31

Notice: memcache_pconnect(): Server memcache_host2 (tcp 11211) failed with: Connection refused (111) in /home/jdoe/memcache-test.php on line 31
PHP Warning:  memcache_pconnect(): Can't connect to memcache_host2:11211, Connection refused (111) in /home/jdoe/memcache-test.php on line 31

Warning: memcache_pconnect(): Can't connect to memcache_host2:11211, Connection refused (111) in /home/jdoe/memcache-test.php on line 31
bool(false)
*/

Expected result:
----------------

bool(true);
bool(false);

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