Smarty template engine fetching data from PHP _php instance

The example in this article describes how the Smarty template engine obtains data from PHP. Share to everyone for your reference. Specifically as follows:

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

Action/Display file: index.php

Copy Code code as follows:

<?php
Creating Smarty Objects
Require_once ("./libs/smarty.class.php");
$smarty = new Smarty ();
$smarty->assign ("AA", "Hello word");//allocation string
$smarty->assign ("BB", 123);//Allocate integral type
$smarty->assign ("CC", 90.8);//distribute float type, floating-point type
$smarty->assign ("DD", true);//allocation string
Allocates an array, the array is generally taken out of the database, here directly to the array
$arr 1 = Array ("Beijing", "Shanghai", "Guangzhou");//index array
$smarty->assign ("arr1", $arr 1);//Allocate index array

$arr 2 = Array ("City1" => "Beijing", "City2" => "Shanghai", "City3" => "Guangzhou");//associative array
$smarty->assign ("arr2", $arr 2);//Allocate associative array

$arr 3 = Array ("Beijing", "Shanghai", "Guangzhou"), Array ("Guan Yu", "Zhang Fei", "Beauty"));
$smarty->assign ("Arr3", $arr 3);

$arr 4 = Array ("AA" =>array ("Beijing", "Shanghai", "Guangzhou"), "BB" =>array ("Guan Yu", "Zhang Fei", "Beauty"));
$smarty->assign ("Arr4", $arr 4);

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 Yellow", $arr 2);
$dog->master = $master;
$smarty->assign ("Dog", $dog);

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

Template file: Index.tpl

Copy Code code as follows:

<p style= "Color:green;" > Fetching string: {$aa}</p>
<p style= "color:red;" > Integer: {$bb}</p>
<p style= "Color:blue;" > Fetching floating-point type: {$CC}</p>
<p style= "Color:orange;" > Boolean value: {$dd}</p>
<p style= "Color:indigo;" > Fetching Array (indexed array): {$arr 1[0]}--{$arr 1[1]}--{$arr 1[2]}</p>
<p style= "Color:green;" > Fetching array (associative array): {$arr 2.city1}--{$arr 2.city2}--{$arr 2.city3}</p>
<p style= "color:red;" > Take two arrays (index, single): {$arr 3[0][0]}</p>
<p style= "color:red;" > Take two sets of arrays (index, traverse All):</p>
<p style= "Color:blue;" > Take a two-dimensional Array (association): {$arr 4.aa[2]}</p>
<p style= "Color:blue;" > Take a two-dimensional array (association, traversal):</p>
<p style= "Color:orange;" > Fetching objects (Normal properties): {$dog->name}</p>
<p style= "Color:orange;" > Fetching objects (Array properties): {$dog->arr.city1}</p>
<p style= "Color:orange;" > Fetching objects (Object properties): {$dog->master->name}</p>
