// Setting a variable in a view file $view->setVar('title', 'My Website'); // Retrieving the value of the variable $title = $view->getVar('title'); echo $title; // Output: My Website
// Setting multiple variables in a view file $view->setVars(['title' => 'My Website', 'author' => 'John Doe']); // Retrieving the value of the 'title' variable $title = $view->getVar('title'); echo $title; // Output: My WebsiteIn this example, we are setting multiple variables in a view file by passing an array of key-value pairs to the setVars function. We are then retrieving the value of the 'title' variable using the getVar function and assigning it to a variable named $title. Finally, we are outputting the value of the $title variable, which should be 'My Website'. This code may also belong to a package/library like Laravel or Symfony, which have their own view systems.
