Smarty specifies the simple use of strings, objects, arrays, etc.

The first is the content of the show. tpl file, which is placed in the templates folder.

The content of the smarty. php file written by myself is as follows:

 "'); $ Smarty = new Smarty (); $ smarty-> left_delimiter =" <{"; $ smarty-> right_delimiter ="}> "; $ smarty-> assign ("str", "hello"); $ smarty-> assign ("integer", 12); $ smarty-> assign ("float ", 100.0); $ smarty-> assign ("bool", true); // Index array $ arr = array ("Shanghai", "Beijing", "Tianjin "); $ smarty-> assign ("arr", $ arr); // associated array $ arr2 = array ('city1 '=> "Shanghai ", 'cit2' => "Beijing", 'city3' => "Tianjin"); $ smarty-> assign ("arr2", $ arr 2); // two-dimensional array $ arr3 = array ("Shanghai", "Beijing", "Tianjin"), array ("Xiaoqian", "Old demon ", "Cai Chen"); $ smarty-> assign ("arr3", $ arr3); $ arr4 = array ("id" => 1, "username" => "wang", "pwd" => "123"), array ("id" => 3, "username" => "xu ", "pwd" => "456"); $ smarty-> assign ("arr4", $ arr4 ); $ arr5 = array ('emp1' => array ("id" => 1, "username" => "wang", "pwd" => "123 "), 'emp2' => array ("id" => 3, "username" => "xu", "pwd" => "456"); $ smarty-> assign ("arr5", $ arr5); $ arr6 = array ('emp1' => array (1, "wang ", "123"), 'emp2' => array (3, "xu", "456"); $ smarty-> assign ("arr6", $ arr6 ); // allocate object class Dog {var $ name; var $ age; var $ color; var $ arr; function _ construct ($ name, $ age, $ color, $ arr) {$ this-> name = $ name; $ this-> age = $ age; $ this-> color = $ color; $ this-> arr = $ arr ;}} // instantiate the object $ dog = new Dog ("James", 11, "RED", $ arr); $ smarty -> Assign ("dog", $ dog); $ smarty-> display ("show. tpl");?>
