Template PHP template engine, which provides the separation of logic and external content, and simple speaking, the purpose is to use PHP programmers to separate, the logical content of the programmer to change the program is not affected by the artist page design. The US re-modify the page does not affect the program logic of the program, which is especially important in multiplayers. Second, Smarty Advantages: 1. Speed: Programs Writing with Smarty can improve the maximum speed, which is relative to other template engine technology. In the middle, no more template recompile (in the case where the source program is not changed) cache technology: Smarty selects a cache technology, which can cache the user's final HTML file into a static HTML page When setting Smarty's Cache property is true, the user's Web request is directly converted to this static HTML file during Smarty, which is equivalent to calling a static HTML file. . Plugin technology: Smarty can customize the plugin. The plugin is actually some custom functions. . The template file is used to use the judgment statement that can be easily reundrained to the template. Third, not suitable for using Smarty: 1. Requires real-time update content. For example, a stock display, it needs to be updated frequently, this type of program uses smarty to slow down the template processing speed. small project. Small projects are quickly and programmers, using Smarty to lose the rapid advantages of PHP development because of the simple projects and programmers and one person. Fourth, install the Smarty class: Installation Smarty's environment: PHP version 4.06 or later. installation Smarty method is very simple, download Smarty.tar.gz from http://samrty.php.net, find the lib directory after decompression, create directory CommM in the current site, and all documents in LIB To copy it into the comm directory, complete the basic installation.

Of course, you can also use this sentence, you can also copy the contents of XXX.TPL to the current statement. {$ name}: Template variable, the core composition in Smarty, uses smarty defined left boundary {and right boundary}, given in the form of PHP variables, will be used in the Smarty program $ smarty -> Assign ("Name", "Li Xiaojun"); replace $ Name in the template into three words of "Li Xiaojun".
