This article describes how to obtain data from php by using the php/20141105125967.html "> smarty template engine. Share it with you for your reference. The details are as follows:

Variable types that can be assigned by smarty ($ smarty-> assign): All data types supported by php-basic data types, composite data types, and special data types (see the smarty related manual for details ).

Operation/display file: index. php

The Code is as follows:

<? Php
// Create a smarty object
Require_once ("./libs/Smarty. class. php ");
$ Smarty = new Smarty ();
$ Smarty-> assign ("aa", "hello word"); // assign a string
$ Smarty-> assign ("bb", 123); // assign an integer
$ Smarty-> assign ("cc", 90.8); // assign float type and floating point type
$ Smarty-> assign ("dd", true); // assign a string
// Assign an array. The array is generally taken from the database.
$ Arr1 = array ("Beijing", "Shanghai", "Guangzhou"); // Index array
$ Smarty-> assign ("arr1", $ arr1); // assign an Index Array

$ Arr2 = array ("city1" => "Beijing", "city2" => "Shanghai", "city3" => "Guangzhou"); // associate an array
$ Smarty-> assign ("arr2", $ arr2); // assign an associated array

$ Arr3 = 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 yellow", $ arr2 );
$ Dog-> master = $ master;
$ Smarty-> assign ("dog", $ dog );

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

Template File: index. tpl

The Code is as follows:

Smarty variable operation

String: {$ aa}

Integer: {$ bb}

Float: {$ cc}

Boolean value: {$ dd}

Array (Index Array): {$ arr1 [0]} -- {$ arr1 [1]} -- {$ arr1 [2]}

Array (associated array): {$ arr2.city1} -- {$ arr2.city2} -- {$ arr2.city3}

Two groups of arrays (index, single): {$ arr3 [0] [0]}

Take two groups of arrays (index, traverse all ):

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

Two-dimensional array (join and traverse ):

Object (common attribute): {$ dog-> name}

Object (array attribute): {$ dog-> arr. city1}

Object (Object attribute): {$ dog-> master-> name}
