PHP smarty Template engine configuration and testing

Smarty Introduction

Smarty is a php template used to write a template engine, it provides a separation of logic and external content, in brief, the purpose is to use a PHP programmer with the Art of separation, the use of programmers to change the logic of the program content does not affect the design of the art page, The artist re-modifying the page does not affect program logic, which is especially important in a multi-person collaborative project.

Advantages:
1. Speed: The program written in Smarty can get the maximum speed improvement, which is relative to other template engine technology.
2. Compiled: The program written in Smarty is compiled into a non-template PHP file at runtime, this file is a mixture of PHP and HTML, the next time you access the template, the Web request directly into this file, Instead of recompiling the template (in case the source program has not changed)
3. Caching technology: Smarty chooses a caching technology that caches the HTML files the user eventually sees as a static HTML page, and when the cache property of the Smarty is set to True, The user's Web request is converted directly to this static HTML file during the Cachetime period set by Smarty, which is equivalent to calling a static HTML file.
4. Plug-in technology: Smarty can customize the plugin. Plugins are actually some of the custom functions.
5. If/elseif/else/endif can be used in the template. The template file can be easily reformatted by using a judgment statement.

Disadvantages:
1. Content that needs to be updated in real time. For example, like a stock display, it needs to update the data frequently, and this type of program uses Smarty to slow down the processing of the template.
2. Small project. Small project because the project is simple and the artist and programmer are in one person's project, using Smarty will lose the advantage of rapid development of PHP.

1. Installation

Download the Smarty package. Unzip and rename to Smarty and put it in the website directory, this example: D:\wamp\www\Smarty

2. Configuration
Modify Include_path in php.ini file
As follows:
; UNIX: "/path1:/path2"
; include_path = ".:/ Php/includes "
; Windows: "\path1;\path2"
include_path = "D:\wamp\www\Smarty\libs"
This example is modified under Windows, and Linux similarly

Create folder under Site Directory-mysmarty, this example path: D:\wamp\www\Smarty\MySmarty
and create 4 sub-folders under it Templates,configs,templates_c,cache
respectively for
1. Storage templates
2. Storing configuration information
3. Storing the compiled files

4. Storing the cache

Set permissions for each folder.
Windows: Right-click Properties--Security--Edit to modify user rights
LINUX:CHMOD directive

3. Testing

Create a index.php file in the Site Directory This example path D:\wamp\www\Smarty\MySmarty

index.php
 
   template_dir = ' D:\wamp\www\Smarty\MySmarty\templates '; $smarty->config_dir = ' D:\wamp\www\ Smarty\mysmarty\configs '; $smarty->cache_dir = ' D:\wamp\www\Smarty\MySmarty\cache '; $smarty->compile_dir = ' D : \wamp\www\smarty\mysmarty\templates_c ';//$smarty->force_compile = true; $smarty->assign ("name", ' Tomorrow '); $ Smarty->display (' Index.tpl ');? >

Establish INDEX.TPL in D:\wamp\www\Smarty\MySmarty\templates

 
  OK, {$name}!

Run index.php and test the settings correctly.
