Detailed explanation of Layout (modular layout) in zend Framework_PHP tutorial
1. First modify the application configuration file
resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
Specify the location of the layout file
2 .Then the easiest way is to modify the bootstrap.php file to add an automatic execution method:
protected function _initDoctype() { }
3. Add a
resources.view[] =
Here we assign a value to the view, although it is just a null value~
4. Add
protected function _initDoctype( )
{
$this->bootstrap('view');//Open the view
$view = $this->getResource('view');//The attempt to get the document. Definition In the main configuration
$view->doctype('XHTML1_STRICT'); //Set the document type
}
5. Finally, let us add a Layout.HTML The file can be found under application/layouts/scripts/
The content is:
doctype() ?>
< ;?php echo $this->headLink()->appendStylesheet('/css/global.css') ?>
layout()->content ?> ;
Then check the page content. If there is a horizontal bar, it means success, and the bar will appear on all pages!

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.

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.
