How to use smarty template 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 realized.

Error message: "SAE_Fatal_error: Uncaught exception 'SmartyException' with message 'unable to write file ./web/templates_c/wrt4e95555280ef1' "

SAE’s solution 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:

Copy the code The code is as follows:

// 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 time, no need to touch

The above three lines are required.

This way the Smarty template can run on SAE.
