smarty复习（smarty复习） Install Smarty and initialize configuration 1.Smarty is written using PHPs face to - face idea, as long as you load Smarty in our PHP script. 2. initialization configuration: $template_dir: template file directory settings $compile_dir: compiled file directory $config_dir: $left_delimiter: is used for left ending variables in the template language, and the default is {, but this default setting conflicts with the Javascript code structure used in the template and is usually subject to modification. For example: { $right_delimiter: $ccaching: tells Smarty whether to cache the output of the template. By default, it is set to 0 or invalid, and you can also set multiple caches for the same template and start caching when the value is 1 or 2. 1 tells Smarty to use the current $cache_lifetime variable to determine whether the cache is expired. 2 tells Smarty to use the cache_lifetime value when the cache is generated. In this way, you can just set the cache lifetime before you get the template so that you can more accurately control when the cache is invalid. $cache_dir: cache directory $cache_lifetime: this variable defines the template cache effective time (seconds). Once this time expires, the cache will be regenerated. If you want to achieve all effects, $caching must be set as true because of the $cache_lifetime requirement. When the value is -1, the cache is forced to never expire. The 0 value causes the cache to always regenerate (a valid way to make the cache invalid is to set $caching=0) Two, Smarty application steps in the application logic layer 1. load 2. set up the image 3. modify the default configuration 4., the dynamically obtained variables in the program are inserted into the template through the assign () method in the Smarty image 5. use Smartys display () method in the image to output the template content. Three, methods 1.assign (string, Varname, mixed, VAR) For example: $smarty-assign (name, Wanglei); Assign the string Wanglei to
