Smarty For SAE (using smarty in sae)_PHP tutorial

Smarty is a very popular template system. It separates business and logic, has fast execution speed, and is widely used in PHP websites.
However, there was a problem when deploying to Sina App Engine (sae). Because sae, as a cloud computing platform, cannot perform file reading and writing operations, the cache files output in Smarty cannot be implemented.
Error message: "SAE_Fatal_error: Uncaught exception 'SmartyException' with message 'unable to write file ./web/templates_c/wrt4e95555280ef1' "
The solution given by SAE is to use Memcache. First enter the application management in the application and enable Memcache initialization in the service management,
Then modify Smarty’s configuration file:

//For SAE compiled files are stored in memcache
$smarty->compile_dir = 'saemc://smartytpl/';
$smarty->cache_dir = 'saemc://smartytpl/';
$smarty->compile_locking = false; // Prevent calling touch, saemc will automatically update the time, no touch is required
The above three lines are required.
In this way, the Smarty template can be run on SAE.
