In a page, some data is cached and some data is not cached, which is partial caching
l $smarty->assign(“var”, “value”, true)
The third parameter: indicates whether not to cache
l {$var nocache=true}
Use nocache parameter after template variable
l {nocache}{/nocache}
Use a pair of nocache tags, everything in between is not cached
Cache file: We found that the name is written directly into the file, and the age needs to be dynamically read every time to implement the local cache function
Try to modify the values of name and age. Pay attention to the variables on the page. The name does not change, but the age changes
7. Multiple caches on a single page
http://localhost/news.php?id=100
View news with id 100
After accessing, a cache file will be generated for this template, and the news with ID 100 will be cached
http://localhost/news.php?id=80
View news with ID 80
At this time, you will see the previous cache file
l $smarty->caching=true
Enable caching mechanism
l $smarty->display(“tpl”, “cacheid”)
The second parameter represents the cache ID, which is the only criterion for a cache file
Code:
We use this URL to access respectively:
Demo07.php?id=10
Demo07.php?id=83
Demo07.php?id=96
Then, it was found that several cache files were generated in the cache directory:
The content before the file name^ is the cache ID, which is the unique identifier of the cache file.
How to clear cache files?
$smarty->clearCache(‘demo07.html’);
Writing like this means clearing all cache files of the demo07 template
$smarty->clearCache(‘demo07.html’,83)
Writing like this means deleting the cache file with ID 83 corresponding to the demo07 template
8. Cache collection
http://localhost/news.php?kid=10&page=8
Indicates that I want to view the news title with the news category ID 10 and display the data on page 8. How to cache it?
l $smarty->caching=true
Enable cache function
l $smarty->display(“tpl”, $id1.”|”.$id2)
Set the cache ID and use | to connect, indicating a cache collection
Code:
Run the following url:
Deo08.php?kid=13&page=2
Deo08.php?kid=25&page=8
Deo08.php?kid=2&page=58
Found that there are several cache files like this in the cache directory
In fact, it means to connect all the obtained parameters with | to generate a new cache file
Applying Smarty in MVC
1.MVC
1. M: Model
2. V: View
3. C: Controller
We just need to replace our previous View component with Smarty
The above introduces php-Smarty-caching 2 (26), including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
