executes the subclass. The non-static code block of the subclass executes and then executes the subclass's construction method.

Using your pity on people who do not agree with you is not the most effective way to promote your claim. Let's take a look at Mr t's example. He bega

The example in this article describes the Smarty implementation of page static (generate HTML) method. Share to everyone for your reference, specific as follows: To reduce the number of database reads, some pages that are not frequently changed, such as the article detail page, need to be made into HTML static pages. In the case of using smarty, you can also implement page statics. Let's say a little bit about the way you normally read dynamically w
