Smarty a method for implementing page statics (generating HTML) _php instance

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 when using Smarty.

Generally divided into these steps:

1. Pass a parameter (ID) by URL;

2, then query the database according to this ID;

3, after obtaining the data according to need to modify the display content;

4, assign need to display the data;

5, display template file.

The Smarty static process simply adds two steps to the process:

First: Use Ob_start () to open the buffer before 1.

Second: Use Ob_get_contents () after 5 to get the memory not output, and then use Fwrite () to write the content to the destination HTML file.

According to the above description, this process is implemented in the site foreground, and content management (add, modify, delete) is usually done in the background, in order to effectively

Using the above process, you can use a small means, that is header (). The specific process is this: after adding and modifying the program, use the

Header () (of course, there are other ways) to jump to the foreground read, so that the page can be HTML, and then after generating HTML to jump back to the background management side, and these two jump

The process is not visible.

<?php
$cachefile = "./cache/demo.html";//put the cached file in a cache folder
$cachetime =20;
if (!file_exists ($cachefile) | | | filemtime ($cachefile) + $cachetime < Time ())//To determine the existence and expiration time
{
  ob_start ();// Output control
  echo ' <table border= "1" width= "align=" center ">";
  Echo ' <caption>
