Custom min version smarty template engine MinSmarty. class. php file and usage, smarty template engine

This article describes the custom min version of the smarty template engine MinSmarty. class. php file. We will share this with you for your reference. The details are as follows:

I. Advantages of smarty

Smarty is a template engine written in PHP and one of the most famous PHP template engines in the industry. It separates the logic code from the external content and provides an easy-to-manage and use method to combine the originally HTML code with the PHP code logic separation. Simply put, the purpose is to separate PHP programmers from front-end personnel so that programmers can change the logic content of the program without affecting the front-end personnel's page design, the re-modification of the page by the front-end personnel does not affect the program logic, which is particularly important in projects with multiple partners.

2. Write a simple smarty template class

The Code is as follows:

<? Php class MinSmarty {// path of the template file var $ template_dir = ". /templates/"; // After the template file is replaced, the file name format is tpl corresponding to com. php var $ complie_dir = ". /templates_c/"; // store the variable value var $ tpl_vars = array (); // use two methods to implement assign and display function assign ($ tpl_var, $ var = NULL) {if ($ tpl_var! = NULL) {$ this-> tpl_vars [$ tpl_var] = $ var ;}// compile the display method implementation function display ($ tpl_file) {// read this template file-> Replace the PHP file that can be run (the compiled file) $ tpl_file_path = $ this-> template_dir. $ tpl_file; // template file path $ complie_file_path = $ this-> complie_dir. "com _". $ tpl_file. ". php "; // The compiled file path // determine whether the file exists if (! File_exists ($ tpl_file_path) {return false;} // do not let every execution generate the compilation file if (! File_exists ($ complie_file_path) | filemtime ($ tpl_file_path)> filemtime ($ complie_file_path) {$ fp1_file_con = file_get_contents ($ tpl_file_path ); // obtain all the content of the template file. // Replace the code {$ title} in the template file with <? Php echo $ this-> tpl_vars ['title'];?> $ Pattern = array ('/\ {\ s * \ $ ([a-zA-Z _] [a-zA-Z0-9 _] *) \ s * \}/I '); $ replace = array ('<? Php echo $ this-> tpl_vars ["$ {1}"];?> '); $ New_str = preg_replace ($ pattern, $ replace, $ fp1_file_con); // The replaced content file_put_contents ($ complie_file_path, $ new_str ); // generate a PHP file for the replaced content} // introduce the compiled file include_once ("$ complie_file_path") ;}}?>

The following code tests the class.

The intro. php code is as follows:

<? Php include_once ("MySmarty. class. php "); $ title =" here is the title "; $ content =" this is content 111111 "; $ MySmarty = new MySmarty (); $ MySmarty-> assign ("title", $ title); $ MySmarty-> assign ("content", $ content); $ MySmarty-> display ("intro. tpl ");?>

The template is as follows:

Intro. tpl:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
