php无法操作memcache

Jun 23, 2016 pm 01:38 PM

我phpinfo()里面显示有memcache了 memcached服务也起了 为何php代码还是不能操作memcache? 不知道该从何排查问题了,在此请教,先谢过。

$memcache = new Memcache();//var_dump($memcache->connect('localhost', 11211));die;if (!$memcache->connect('localhost', 11211))  die('could not connect');$memcache->set('key', 'test');$get_value = $memcache->get('key');echo $get_value;       
Copy after login

网页访问这个php返回absorted状态

phpinfo()里面显示有memcache了 memcached服务也起了

memcache与memcached是不同的。

后台进程确认一下服务器端是否正常

memcache是客户端,memcached是服务端服务
我说 phpinfo()里面显示有memcache了,就是想表达php的memcache扩展我已经安装上了。
现在的问题就是 扩展装了,服务起了,php还是没法操作memcache~

后台进程确认一下服务器端是否正常



我确认了,服务端是正常的。
我用telnet localhost 11211能正常连接memcache并且进行存储读取的操作。

现在的问题时 php无法操作memcache。

absorted状态 应该是客户端断开了,而不是服务端断你开了
多发生与浏览器中

仅php代码不会是这样的
建议你先确定 php 的错误检查没有被关闭,错误显示是打开的

<?phpini_set('display_errors', 1);$memcache = new Memcache();var_dump($memcache);die();//加上这一行浏览器访问就不是absorted状态if (!$memcache->connect('localhost', 11211))  die('could not connect');$memcache->set('key', 'test');$get_value = $memcache->get('key');echo $get_value;
Copy after login


加上第五行die(); 浏览器就不是absorted状态,返回object(Memcache)#1 (0) { } 
再后续调试 发现问题时出在$memcache->connect 这里,这一段导致了absorted吧

把 localhost 改成 127.0.0.1 看看

另外 echo $memcache->getVersion();
也可以看到是否正常

另外 echo $memcache->getVersion();
也可以看到是否正常



改成localhost也还是同样的错误
$memcache = new Memcache();
echo $memcache->getVersion();

这样的话会出: Warning: MemcachePool::getversion(): No servers added to memcache connection in xxx line 5
我尝试$memcache = new Memcache();$memcache->addserver('127.0.0.1', 11211);  依然absorted

$memcache = new Memcache();
$memcache->connect('localhost', 11211);
echo $memcache->getVersion();
如果未连接上,就会报错

我重新下了个stable 版的memcache解决了问题

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
