wampserver configuration memcache, wampservermemcache_PHP tutorial

wampserver configures memcache, wampservermemcache

The environment I use is win7 64-bit operating system, wampserver is also 64-bit, the version is 2.5, and the php version it comes with is 5.5 .

Steps to configure memcache:

The first step is to download the memcahed.exe and php_memcache.dll extensions. Download address: http://pan.baidu.com/s/1jG8OREu

The second step is to install memcache and configure memcache extension. Unzip the compressed package of memcache.exe to the bin directory of wampserver, which is at the same level as the directory of php.

Then execute the command in the picture in dos; Note: Replace the path in the picture below with the path where your memcached.exe is located.

Next, configure the mecahce extension of php and place php_memcache.dll in the ext directory of php. My directory is D:wampbinphpphp5.5.12ext;

Then add a line extension=php_memcache.dll in php.ini, be careful not to add a semicolon in front. Then restart the wampserver service.

Note: Because no error was reported when restarting wampserver when configuring memcache, I did not detect memcache in phpinfo. So I can only test the code directly. I was lucky and the configuration was successful.

Here is the code I used to test:

Output:

This configuration is successful! If there are any mistakes, please correct them if you see them.

Attached here are some functions commonly used by PHP to operate memcache:

Memcache::add adds a value, if it already exists, returns false

Memcache::addServer adds a server address for use

Memcache::close closes a Memcache object

Memcache::connect creates a Memcache object

memcache_debug controls debugging function

Memcache::decrement subtracts the value in a saved key

Memcache::delete deletes a key value

Memcache::flush clears all cached data

Memcache::get gets a key value

Memcache::getExtendedStats Gets the running system statistics of all processes in the process pool

Memcache::getServerStatus Gets the parameters for running the server

Memcache::getStats returns some running statistics of the server

Memcache::getVersion returns the version information of running Memcache

Memcache::increment performs an addition operation on the value in a saved key

Memcache::pconnect creates a Memcache persistent connection object

Memcache::replace overwrites an existing key

Memcache::set adds a value or overwrites it if it already exists

Memcache::setCompressThreshold compresses data larger than a certain size

Memcache::setServerParams Modifies server parameters at runtime
