How does php operate memcache?

To use memcached in PHP first download the memcached-client.php, after downloading the memcached-client.php, you can operate the memcached service through the class "memcached" in this file. In fact, code calls are very simple. The main methods used are add (), get (), replace (), and delete (). The methods are described as follows: add ($ key, $ val, $ exp = 0) writes an object to memcached. $ key is the unique identifier of the object. $ val is the data of the written object. $ exp is the expiration time, in seconds, the default value is unlimited; get ($ key) www.phpnewer.com/index.php/Tszj/detail/id/404

The memcache module cannot be found in php.

1. Write a phpinfo file to view the file <? Php phpinfo ();?>
2. Search for php. ini in phpinfo and find the location of php. ini. Make sure that the modified php. ini and the actually running php. ini are a file.
3. Check whether the ext directory in php. ini contains the php_memcache.dll directory for you.
4. Check whether the ext directory of php is in the system environment variable.
