// Assign a value to a variable $smarty->assign_var('title', 'My Website'); // Use the variable in a template {{ $title }}
// Assign an array to a variable $colors = array('red', 'green', 'blue'); $smarty->assign_var('colors', $colors); // Use the array in a template {% for color in colors %} {{ color }} {% endfor %}In this example, an array of colors is assigned to the variable `$colors` using `assign_var`. The array is then used in a template to display each color using a loop. This code likely uses a web development framework such as Twig or Blade. Based on these examples, it seems that `assign_var` belongs to an object-oriented PHP template library such as Smarty or Twig.
