Smarty Test

Total is {$total}

Formatted Total is {$total|number_format}

$smarty->assign("total",$total); //Assign values ​​to variables in the template $formatted_total = number_format($total); //Format $total $smarty->assign("formatted_total",$formatted_total); //Assign values ​​to variables in the template $smarty->display('test1.htm'); //Display page ?>
test1.html template code:
1 2 3 4 5 6 7 8 9 Smarty Test

Total is {$total}

Formatted Total is {$formatted_total}

Compiled test.html.php code:
1 2 3 4 5 6 7 8 9 10 11 12 13 compiled from test1.htm */ ?> Smarty Test

Total is _tpl_vars['total']; ?>

Formatted Total is _tpl_vars['formatted_total']; ?>

The test1.html template can be rewritten as test2.html like this:
1 2 3 4 5 6 7 8 9 Smarty Test

Total is {$total}

Formatted Total is {$total|number_format}

Then the corresponding test.php code is changed to:

1

2

4

5

6

7

require 'libs/Smarty.class.php'; //包含Smarty类库文件

$smarty = new Smarty; //创建一个新的Smarty对象

$total = 12345;

$smarty->assign("total",$total); //对模版中的变量赋值

$smarty->display('test2.htm'); //显示页面

?>

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
