In php, smarty variable modifier usage instance analysis _ php instance

This article mainly introduces the usage of smarty variable modification in php, and analyzes common techniques of smarty template variable modification. For more information, see the example below. Share it with you for your reference. The specific implementation method is as follows:

Test. php code:

<? Php require 'libs/Smarty. class. php '; // contains the Smarty class library file $ smarty = new Smarty; // creates a new Smarty object $ total = 12345; // assign $ total $ smarty-> assign ("total", $ total); // assign $ formatted_total = number_format ($ total) to the variable in the template ); // format $ total $ smarty-> assign ("formatted_total", $ formatted_total); // assign $ smarty-> display('test1.htm') to the variables in the template; // display the page?>

Code of the test1.html template:

        Smarty Test           Total is {$total}     Formatted Total is {$formatted_total}     

Compiled test.html. php code:

<?php /* Smarty version 2.6.22, created on 2009-03-19 14:37:39      compiled from test1.htm */ ?>         Smarty Test           Total is <?php echo $this->_tpl_vars['total']; ?>      Formatted Total is <?php echo $this->_tpl_vars['formatted_total']; ?>      

The test1.html template can be rewritten as test2.html:

        Smarty Test           Total is {$total}     Formatted Total is {$total|number_format}     

The corresponding test. php code is changed:

<? Php require 'libs/Smarty. class. php '; // contains the Smarty class library file $ smarty = new Smarty; // creates a new Smarty object $ total = 12345; $ smarty-> assign ("total ", $ total); // assign a value to the variable in the template $ smarty-> display('test2.htm'); // display the page?>

Browser display:

Total is 12345
Formatted Total is 12,345
