Zend Framework implementation of Zend_view Integrated Smarty template system _php instances

This paper describes the method of Zend Framework to implement Zend_view integrated Smarty template system. Share to everyone for your reference, as follows:

Zend_view abstracts out the zend_view_interface, allowing us to integrate different view solutions, such as the integration of Smarty. To use a different view system as a view in Zend, just implement the Zend_view_interface interface.

Interface definitions for Zend_view_interface:

The basic implementation of the integrated Smarty is as follows:

If you need to configure Smarty, you can open the/zf_demo1/library/smartylib/smarty.class.php file for appropriate configuration such as

/*** Initialize new Smarty object**/public function __construct () {//Selfpointer    Needed by some other class methods $this->smarty = $this;    if (is_callable (' mb_internal_encoding ')) {mb_internal_encoding (smarty::$_charset);    } $this->start_time = Microtime (true); Set Default dirs $this->settemplatedir ('/www/zf_demo1/temp/smarty '). Ds. ' Templates '. DS)->setcompiledir ('/www/zf_demo1/temp/smarty '). Ds. ' Templates_c '. DS)->setpluginsdir (smarty_plugins_dir)->setcachedir ('/www/zf_demo1/temp/smarty '). Ds. ' Cache '. DS)->setconfigdir ('/www/zf_demo1/temp/smarty '). Ds. ' Configs '.    DS); $this->debug_tpl = ' file: '. DirName (__file__).    '/debug.tpl ';    if (Isset ($_server[' script_name ')) {$this->assignglobal (' script_name ', $_server[' script_name ']); }}
