How to implement smarty template engine to assign data types
This article mainly explains "how to achieve smarty template engine allocation of data types", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "how to achieve smarty template engine allocation of data types" bar!
The specific analysis is as follows:
I. Distribution of basic data
/ / assign basic data $smarty- > assign ("str", "hello smarty!"); $smarty- > assign ("int", 12.1344); $smarty- > assign ("double", 12.1344); $smarty- > assign ("bool", true); $smarty- > assign ("bool2", false); string type: integer: floating point: Boolean true: Boolean false:
The browser displays the results:
1 for true, 0 for false, false for null, showing nothing.
Second, allocate the array of composite data
/ / indexed array $res=array ('Shanghai', 'Beijing', 'Shenzhen'); $smarty- > assign ("arr", $res); / associative array $res2=array ('city1'= >' Beijing', 'city2'= >' Guangzhou', 'city3'= >' Hunan'); $smarty- > assign ("arr2", $res2); / / indexed 2D array $res3 = array ('Xiaoxiao', 'Changshan','Wu Bei'), array ('Shanshan', 'Chang Ming') $smarty- > assign ("arr3", $res3); / / the associated two-dimensional array $res4 = array (array ('id'= >' 001), email'= > 'zhangsan@1163.com'), array (' url'= > 'http://www.baidu.com','age'=>'28')); $smarty- > assign ("arr4", $res4) / / an associative 2D array of 2 $res5=array ('emp1'= > array (' id'= > '001'), email'= > 'zhangsan@1163.com'),' emp2'= > array ('url'= >' http://www.baidu.com','age'=>'28')); $smarty- > assign ("arr5", $res5)
Template file
Indexed array: element 1, element 2, element 3: associative array 1 (not recommended): element 1, element 2, element 3: associative array, element 2 (recommended): element 1, element 2, element 3: two-dimensional indexed array: element 1, element 2, element 3: element 1, element 2, element 3, element 4, element 5: associative two-dimensional array form 1: id-, name-, email- Url-, age- associative two-dimensional array form 2: id-, name-, email-, url-, age-
The browser displays the results:
Third, the object of assigning compound data
Class Master {var $name; var $age; function _ _ construct ($name,$age) {$this- > name=$name; $this- > age=$age;}} class Dog {var $name; var $age; var $color; var $arr; var $master; function _ construct ($name,$age,$color,$arr6,$master) {$this- > name=$name; $this- > age=$age; $this- > color=$color; $this- > arr=$arr6; $this- > master=$master;} $arr6=array $dog1 = new Dog ('Xiaobai', 1MagneWhitekeeper Magnum Arr6 magic master); $smarty- > assign ("dog", $dog1)
Template file
Object: / / basic properties name-name} >, age-age} >, color-color} > / / array properties arr-arr [0]} >, arr-arr [1]} >, arr-arr [2]} > / / object properties object-master- > name} >, object-master- > age} >
The browser displays the results
