How smarty template engine obtains data from php, smarty template

The example in this article describes how the smarty template engine obtains data from php. Share it with everyone for your reference. The details are as follows:

Smarty can assign ($smarty->assign) variable types: all data types supported by PHP - basic data types, composite data types, special data types (see smarty related manuals for details).

Operation/display file: index.php

Copy code The code is as follows:

//Create smarty object
require_once("./libs/Smarty.class.php");
$smarty = new Smarty();
$smarty->assign("aa","hello word");//Assign string
$smarty->assign("bb",123);//Assign integer
$smarty->assign("cc",90.8);//Assign float type, floating point type
$smarty->assign("dd",true);//Assign string
//Allocate an array. The array is usually taken out from the database. Here it is directly assigned to the array
$arr1 = array("Beijing","Shanghai","Guangzhou");//Index array
$smarty->assign("arr1",$arr1);//Assign index array

$arr2 = array("city1"=>"Beijing","city2"=>"Shanghai","city3"=>"Guangzhou");//Associative array
$smarty->assign("arr2",$arr2);//Assign associative array

$arr3 = array(array("Beijing","Shanghai","Guangzhou"),array("Guan Yu","Zhang Fei","Beauty"));
$smarty->assign("arr3",$arr3);

$arr4 = array("aa"=>array("Beijing","Shanghai","Guangzhou"),"bb"=>array("Guan Yu","Zhang Fei","Beauty") );
$smarty->assign("arr4",$arr4);

//Object type
class Master{
public $name;
public $address;
}
$master = new Master();
$master->name="Baidu";
$master->address = "Zhongguancun";
class Dog{
public $name;
public $age;
public $color;
public $arr;
public $master;
function __construct($name,$age,$color,$arr){
$this->name = $name;
$this->age = $age;
$this->color = $color;
$this->arr = $arr;
}
}
$dog = new Dog("puppy",4,"golden",$arr2);
$dog->master = $master;
$smarty->assign("dog",$dog);

$smarty->display("index.tpl");
?>

Template file: index.tpl

Copy code The code is as follows:

smarty variable operation

Get string: {$aa}

Take an integer: {$bb}

Take floating point type: {$cc}

Take Boolean value: {$dd}

Get array (index array): {$arr1[0]}--{$arr1[1]}--{$arr1[2]}

Get array (associative array): {$arr2.city1}--{$arr2.city2}--{$arr2.city3}

Get two sets of arrays (index, take a single): {$arr3[0][0]}

Get two sets of arrays (index, traverse all):

Get a two-dimensional array (association): {$arr4.aa[2]}

Get a two-dimensional array (association, traversal):

Get the object (common attributes): {$dog->name}

Get the object (array attribute): {$dog->arr.city1}

Get the object (object attribute): {$dog->master->name}
