ubuntu 下使用 memcache ::delete() 報錯解決方案

ubuntu10.10 desktop,安裝了memcached

delete 使用方式：

$mem = new Memcache; 

$mem->connect('127.0.0.1',11211); 

$mem->delete('key');

報錯信息：

coinsight@insight-ubuntu:~$ php clear.php   PHP Notice:  MemcachePool::delete(): Server 127.0.0.1 (tcp 11211, udp 0) failed with: CLIENT_ERROR bad command line format.  Usage: delete <key> [noreply]  (0) in /home/coinsight/clear.php on line 4  coinsight@insight-ubuntu:~$ 

解決方案：在使用delete方法時，如：$memcache->delete('key', 0) 加個參數 可以設爲0(0表示立即刪除)  或者是其他一個數值 如10 表示10秒後刪除

the Memcache::delete(key) function is broken on several combinations of memcached+pecl-memcache combinations. 

pecl-memcache 2.2.5 + memcached 1.4.2 - Memcache::delete(key) WORKS

pecl-memcache 2.2.5 + memcached 1.4.3 - Memcache::delete(key) DOES NOT WORK

pecl-memcache 2.2.5 + memcached 1.4.4 - Memcache::delete(key) WORKS

pecl-memcache 2.2.5 + memcached 1.4.5 - Memcache::delete(key) WORKS

pecl-memcache 3.0.4 + memcached 1.4.2 - Memcache::delete(key) WORKS

pecl-memcache 3.0.4 + memcached 1.4.3 - Memcache::delete(key) DOES NOT WORK

pecl-memcache 3.0.4 + memcached 1.4.4 - Memcache::delete(key) DOES NOT WORK

pecl-memcache 3.0.4 + memcached 1.4.5 - Memcache::delete(key) DOES NOT WORK
