Php memcache installation and precautions

Install php Tutorial extension: Steps for memcache in windows

1. Download php extension dll: http://downloads.php.net/pierre/

2. Put. dll under the extension directory of php, which is generally in the ext folder of the php directory.

3. Modify php. ini in the bin folder under the apache Directory, and add extension = php_memcache.dll.

4. Restart the apache server and use phpinfo () to check whether the memcache configuration is correct.

It is worth noting that:

You must pay attention to the php compilation version. When downloading memcache, pay attention to the same compilation version. For example, if php is compiled using vc6, memcache should also be compiled using vc6.
